Cisco broadens its video vision

admin — Tue, 24 Jun 2008 04:03:56 +0000

Cisco this week announced plans to purchase Denmark-based DiviTech A/S, a provider of digital service management systems, as part of a broader video strategy and product launch. DiviTech’s DSM products offer media broadcasters, cable and IPTV service providers an intuitive interface for creating, modifying and managing video networks, Cisco says. DiviTech’s DSM technology includes a software application that will allow service providers to centrally provision and deliver localized content, such as local and regional news and on-demand video and services, within a specific geography. (Catch up on 2008’s hottest tech M&A deals to date here.)
Cisco plans to integrate DiviTech’s DSM product with its ROSA network and element-management system to create a platform that offers digital video element, network and service management in a single product. (Compare video collaboration products.)
DiviTech marks Cisco’s 128th acquisition.
The deal is subject to various standard closing conditions and is expected to be finalized in Cisco’s fourth quarter of fiscal year 2008. Financial terms of the transaction are undisclosed.
Cisco plans to integrate DiviTech into its Digital Media business unit as part of the Service Provider Video Technology Group. DiviTech employees will move into Cisco’s Copenhagen facility.
On the product front, Cisco unveiled video surveillance modules for its Integrated Services Router (ISR) platform. The modules are intended to converge physical security over an IP network but are also designed to support non-IP video surveillance equipment to enable a migration to IP-based surveillance. Cisco has more than 4 million ISR branch router customers. Video surveillance is one of a number of services that run on the ISR, which also supports
unified communications, network security, VPNs and mobility.
The video surveillance modules for the Cisco 2800 and 3800 series ISRs include:

* Video Management and Storage System

(VMSS) Network Module, which helps enable local archival and management of video images. VMSS lets customers manage and monitor multiple video sources through a single converged interface, Cisco says. It supports Cisco and third-party IP cameras.

* IP Video Surveillance 16-Port Analog Video Gateway Network Module, which provides high-density analog video encoding, as many as 30 frames per second per port at as many as 4CIF video resolution, support for Motion JPEG and MPEG4, remote Pan Tilt Zoom camera control, integrated contact closure ports, and embedded motion detection. Cisco also rolled out video surveillance modules for its 3200 series ISR, which is designed for environmentally challenging outdoor and mobile environments.The Cisco IP Video Surveillance 4-Port and 2-Port Intelligent Video Gateway PC-104 cards provide video surveillance capabilities for mobile workers, such as first responders and transportation operators, as well as outdoor fixed environments, such as kiosks and traffic lights. Physical security specialist ADT will resell the new Cisco products. Cisco also enhanced its Digital Media System (DMS) for enterprises. Among the new features are an interactive application, called Enterprise TV, a new digital media player, and expanded functionality for the company’s existing digital signage and desktop video applications.

The 18-month-old DMS system has more than 600 customers across financial services, retail, education, sports, entertainment and other industries. DMS Release 5.0 includes Cisco Enterprise TV, an application that allows organizations to deliver on-demand video and broadcast live TV channels over an IP network to digital displays. With a remote control, users can access content through on-screen menus and program guides, and organizations can create and customize lineups and content libraries. The new media player is the DMP 4400G. This is an IP endpoint that enables digital signage and Enterprise TV through the ability to play high-definition live and on-demand video, motion graphics, Web, and dynamic content on digital displays. The DMP 4400G includes hardware options of up to 4 gigabytes of local storage and support for MPEG-4/H.264 and Adobe Flash 9. The existing DMP 4305G model supports standard-definition and high-definition MPEG-2, RSS, and other Web formats and dynamic data. For digital signage, DMS 5.0 applications now support digital signage content such as Flash 9 video, scrolling tickers and emergency notifications. This application uses the same hardware and management platform as Cisco EnterpriseTV. For desktop video, DMS 5.0 includes new content-level viewing security options, more detailed usage reporting, the ability to share content and embed videos into Web pages or other applications, closed captioning, and video portal support for non-English languages. Customers of the Cisco Wide-Area Application Services WAN optimization product can use it with DMS 5.0 without making additional infrastructure investments, Cisco says. Pricing and availability of the ISR modules and DMS 5.0 could not be learned by press time.

5 ways insiders exploit your network

admin — Wed, 14 May 2008 07:59:45 +0000

Cox Communications employee William Bryant recently pleaded guilty to information technology sabotage, having caused the loss of computer, telecommunications and emergency 911 services for thousands of Cox’s business and residential customers throughout Dallas, Las Vegas, New Orleans and Baton Rouge . Bryant faces a 10-year jail sentence and a $250,000 fine, but the future is less certain for Cox. Although services were fully restored, the incident’s effect on Cox’s reputation has yet to be determined.

The Cox story, along with recently publicized incidents at NASA, Accenture, Gap and Medco, serve as a harsh reminder that insiders represent a common and often misunderstood threat. Data theft and sabotage can result in hard costs, compliance-related problems, legal fees, productivity loss and, possibly most costly, loss of reputation.(Compare Data Leak Protection products.)

Insider threats are up 17%, according to the latest Computer Security Institute survey (a trend echoed by recent surveys by Deloitte and by CSO magazine). As IT and communication systems grow in complexity, so too do the numbers of employees, contractors and managed service providers required to maintain them. The spike in threats is not surprising given the often unfettered and unmonitored access these insiders have to critical corporate networks.

It should be clear that companies need to monitor insiders as aggressively as they do outsiders. However, policing insiders can prove challenging given the privileged access they require to do their jobs. Here are the five most common methods insiders use to access network resources and simple measures enterprise IT can take to protect against the implied threats.

1. Modems.

A lack of central management combined with easy-to-guess static passwords make modems an ideal entry point for insiders with detailed knowledge of a network. Many companies have tried to address this challenge by simply unplugging modems until needed. However, unplugging modems makes it impossible to use them for their intended purpose, namely remotely restoring critical systems in times of emergency or outage.

Given that modems are a necessity, enterprises must extend the same security and identity confirmation measures to modems that they do to other remote-network entry points. Extending corporate two-factor authentication measures to modems or replacing legacy modems with newer, more secure models with embedded multifactor authentication can provide appropriate and cost-effective protection.

2. Open file transfer.

Most organizations use open file transfer to patch network infrastructure. Internal technicians and vendors use this poorly secured, unrestricted access to troubleshoot, apply appropriate fixes and correct problems. However, they also can misuse this freedom to change files, remove critical components or disrupt systems, resulting in nonoperational systems, Web site defacements, data theft and other damaging situations. A disgruntled or former employee could have the knowledge and motivation to commit such acts. However, more often, an insider threat can be less dramatic but equally troublesome. Even well-intentioned employees can be careless or make inadvertent mistakes. As such, protecting information assets requires you to have control over who can upload and download files, and a clear and easily retrievable record of all changes made to the system and the person who made them.

Traditionally, limiting and monitoring open file transfer required that individual permissions be set on each machine, causing headaches for IT departments. However, new technologies, such as vendor access and control (VAC) systems, can limit access and monitor activities organizationwide or for specific systems.

3. Open telnet and SSH ports.

Companies that use third parties to remotely access and troubleshoot systems should properly secure or close telnet and SSH ports. Without these protections in place, all a remote technician needs is a single internal IP address to get anywhere on your network without your knowledge. It is dangerous to assume that remote technicians have limited knowledge of your IP addressing schemes, as it is possible the same technician has worked on site at your facility. Also, infrastructure equipment often shares one easily guessed password, making it simple for an insider to access unauthorized equipment.

As a standard practice, it is recommended that companies restrict thirdparty access via telnet or SSH to systems beyond the typical scope of their services, unless the session is recorded or actively shadowed by a member of your team. Alternatively, many organizations use intermediary systems to create a proxy for these sessions, adding the needed level of control and tracking.

4. Server console ports.

Technicians frequently connect to serial console ports, very often on routers and Linux/Unix servers. To provide scalable access, companies will typically connect to serial console ports using terminal servers. However, terminal servers, by default, offer minimal security. By gaining access to a single terminal server, an insider can access and potentially disable thousands of systems. As such, it is recommended that companies regularly review terminal server security capabilities and place security devices outside the console ports of systems hosting sensitive data (for example, financial records, customer data and human resources information).

5. Unmonitored extranet traffic.

Extranets provide a convenience for companies, allowing them to open their networks to vendors, customers and partners to support real-time collaboration. Extranets (for example, IPSec, SSL, remote desktop) work reasonably well when the number of systems to be shared with outsiders is small and the authorization level on those systems can be tightly controlled.
However, typical extranets, where access to many systems is required or where high-level authorization must be granted, can be problematic.

Often, too much access is granted inadvertently, and activities cannot be closely monitored and controlled. As opposed to typical extranets, vendor access and control systems offer the extra layer of control needed to prevent sabotage and data theft.

While many third-party providers are trustworthy, it is risky to make that assumption. Regardless of whether employees and/or third-party providers access your network, human motivations remain the same. With any insider, there is the prospect of misuse, possibility of mistakes, and opportunity for theft. Increased awareness combined with a few protective measures can reduce the risk.

7 dirty secrets of the security industry

admin — Thu, 08 May 2008 07:54:43 +0000

Corporate IT executives need to beware the seven dirty secrets of the security industry that can undermine the safety of business networks, a security expert told attendees at Interop Las Vegas.“It’s best to have a healthy level of skepticism about what security vendors are trying to tell you,” says Joshua Corman, principal security strategist for IBM/ISS, which itself is a security vendor.
He called his talk “Unsafe at any speed: 7 Dirty Secrets of the Security Industry,” harkening back to the 1960s’ Ralph Nader book about automobile safety, Unsafe at Any Speed. Nader’s book took car makers to task for worrying more about cosmetic improvements that upgrades to make cars more safe.
Security vendors have at times invested development money in management GUIs rather than new security features. And they have a tendency to add features only when customers demand them, he says. “The goal of the security vendor is not to secure, it’s to make money,” Corman says.
He says that is his “zeroth” dirty secret of the security industry. These are the other seven:
1. Antivirus certifications are misleading.
The certification standards confirm that devices block 100% of all replicating malcode. The catch is that 75% of malcode coming into networks is non-replicating, such as Trojans. When the standard was set, non-replicating malcode represented 5% of malcode, Corman says. “Certification means [a product] caught 100% of 25% of the bad stuff,” he says. (Compare antivirus products)
2. There is no perimeter.
Vendors say that the network perimeter must be defended, but most data that is actually lost doesn’t go through the firewall. Half of all breaches are the result of either lost laptops or lost thumb drives or other removable media. Businesses need to tighten up their business processes at least as much as they need to tighten up network perimeters, he says. “If you still believe in perimeters, you may as well believe in Santa Claus,” he says.
3. Risk analysis threatens vendors.
Security vendors want businesses to buy what they sell, so they push specific products to block specific threats. NAC, for example, might solve a real problem. But if the problem doesn’t have a major impact on the company’s top three business priorities, it probably doesn’t need to be addressed. Risk assessment may determine that improved business processes or hardening configurations of existing gear are all that are needed, Corman says. “You need to understand the environment and the big priorities,” he says.
4. There is more to risk than just weak software.
Security vendors push protecting against software vulnerabilities, but those flaws don’t represent the source of the bulk of successful exploits, Corman says. Weak passwords, weak configurations of devices – particularly default configurations – and weak people – easy victims of social engineering, are bigger problems, he says. “If software were perfect, we’d still have viruses, Trojans, etc., that don’t need software flaws to work,” he says.
5. Compliance threatens security.
Compliance itself is not bad, but complying with security standards set by government, such as HIPAA, or industries, such as PCI, are not enough to keep networks secure, Corman says. The problem is that regulations create a budget and resource conflict between what compliance demands and what network executives think really needs doing to best secure the business it supports. Complying with such standards also signals to potential attackers the exact defenses businesses have. “If PCI tells them where the fortifications are and they start targeting other areas,” he says. (Compare Network Auditing and Compliance products)
6. Vendor blind spots allowed the Storm worm outbreak to happen.
Corporate defenses that check behavior of network devices can spot machines taken over by the bot network, but there is no such protection for consumer networks. Behavior-based antivirus software for endpoints and anomaly detection systems also work, but not for those who don’t have them, he says. “Storm recognized the biggest blind spots in antivirus and exploited them, and Storm employs great social engineering,” Corman says.
7. Security has grown well past do-it-yourself.
Security vendors try to convince businesses that security is so complex that they cannot possibly do it alone, Corman says. But the security needs of businesses are so individual that merely choosing a product is not enough. “It’s not enough to have the right tool. It needs to be installed and configured properly for the environment,” he says, and that can best be done by the IT staff itself.

5 IT skills that won’t boost your salary

admin — Mon, 05 May 2008 08:43:47 +0000

It no longer pays to be a PC, NetWare or HTML expert

Technical skills may never die, but areas of expertise wane in importance as technology advances force companies to evolve and IT staff to forsake yesterday’s craft in favor of tomorrow’s must-have talent. “There is less need for system-side knowledge. In the past, IT folks had to understand a lot about memory, drivers and address locations, and what used which interrupt, but nowadays that stuff is plug-and-chug even on many Unix systems,” says Brian Jones, manager of network engineering at Virginia Polytechnic Institute and State University’s Tech Communications Network Services unit in Blacksburg. “I feel like all the skills I have picked up along the way are valuable and help shape my thinking and troubleshooting abilities. I don’t know how to value or devalue these skills; it’s like theyhave taken on new value now.” Industry watchers would be hard pressed to name specific IT skills as entirely dead or completely useless, but some skills are well on their way to being considered a thing of the past — as reflected by the declining pay associated with them. As hot skills like virtualization rise to the top of company must-have lists, high-tech talents in certain operating systems and specific vendor products fall to the bottom.

Here are five high-tech skills that don’t demand the pay they once did.

Plain old HTML

As companies embrace Web 2.0 technologies such AJAX, demand for skills in HTML programming are taking a back seat. According to Foote Partners, pay for skills in technologies such as Ajax and XML increased by 12.5% in the last six months of 2007, while IT managers say they don’t see a demand for technology predecessors such as HTML. “I’m not seeing requirements for general Web 1.0 skills — HTML programming skills,” says Debbie Joy, lead solution architect for CSC in Phoenix. Legacy programming languages Skills in programming languages such as Cobol, Fortran, PowerBuilder and more don’t rate like they once did. “Certainly the Cobol people that had a resurgence with the Y2K bug aren’t in demand,” says John Estes, vice president of strategic alliances of Robert Half Technology, an IT staffing consultancy. “Certain other applications such as Delphi and PowerBuilder, [which were] very big in the ‘90s, are no longer in demand.” IT work-force and compensation research conducted by Foote Partners revealed that Cobol, PowerBuilder and Jini noncertified skills were among the lowest-paying skills in the second half of 2007. David Foote, CEO and chief research officer at Foote Partners, says the research shows not that such skills aren’t in use today but that companies aren’t willing to pay for them. “There is still a lot of C and Cobol around, though these skills are worth very little paywise,” Foote says.

NetWare

Operating system know-how continues to be in top demand among hiring managers, but expertise in Novell’s network operating system NetWare isn’t keeping up with other technologies in the same area. “Networking software such as Net- Ware isn’t near what it was in the ‘90s,”

Estes says. And Foote adds, “Windows Server and Linux skills have replaced, or are replacing, NetWare skills” in terms of demand.

Non-IP network

IP and Internet skills usurped non-IP network expertise and know-how in technologies such as IBM’s System Network Architecture (SNA) continue to rank among the lowest-paying skills. “For

networking, IP skills have replaced SNA skills,” Foote says. According to Foote Partners’ research, SNA skills accounted for just 2% of base pay in the fourth quarter of 2007, while security skills made up 17% of base pay.

“Mainframe computing skills, including network components such as SNA, are no longer required in a server-based IP networking environment,” says Martin Webb, manager of data network operations, Ministry of Labour and Citizens’ Services, Province of British Columbia.

PC tech support

The Computer Technology Trade Association (CompTIA) reports that hardware skills and knowledge, including expertise with printers and PCs, are on the decline in terms of demand. Comp- TIA surveyed 3,578 IT hiring managers to learn which skills would grow in importance over time and the industry organization found: “The skill area expected to decline the most in importance is hardware.” Foote Partners’ research separately showed an 11.1% decline in pay over the last six months of 2007 for ITIL skills, which are often put in place to streamline IT service management and help desk efforts. “The ‘move, add and changes’ PC tech function isn’t quite what is used to be,” Robert Half Technology’s Estes says

Wanted: 10 IT skills employers want

admin — Mon, 05 May 2008 08:04:57 +0000

Technology pros looking to find new work or secure their current jobs should get schooled on wireless, Web 2.0 and virtualization. It would also be to their advantage to spend some time boning up on business basics.
“IT professionals with the right technical skill set plus a foundational understanding of the business they work in will stand a much better chance in today’s market,” says Neill Hopkins, vice president of skills development at the Computer Technology Industry Association(CompTIA).
Business initiatives such as enterprise mobility, data center consolidation and UC are driving demand for expertise in new technology areas and reinforcing the importance of mastering the fundamentals such as networking and security,industry watchers say.
“Web 2.0, .Net, Java, wireless — skills in technologies that enable end users to engage
and communicate with each other — are hot,” says Rich Milgram, CEO of online
job portal Beyond.com. “At the same time network and security skills are becoming
more and more important, especially as companies expose more and more of their networks and data to the world.”
Here we examine (in no particular order) the current most-sought-after skills and those destined to be in demand going forward.

1. Wireless

Because end users expect to be able to work from anywhere anytime, skills in wireless and mobility are being pushed to the top of many hiring managers’ must-have lists.
“Now you need to be able to plan and troubleshoot radio interference and access point placement. Everyone wants to work from anywhere,” says Bruce Meyer, director of network services at ProMedica Healthcare in Toledo, Ohio. “Standards will continue to evolve rapidly as everyone chases the Holy Grail of a wirelike experience. I’m not just looking for wireless skills; I’m looking for the ability to rapidly learn new things.”

According to CompTIA, wireless skills in many areas — 802.11, WiMAX and broadband — will only become more appealing to companies in the next five years.
John Estes, vice president of strategic alliances at Robert Half Technology, adds that mobility goes beyond knowing wireless technologies. It also requires knowing about each device end users might start using to tap the network. “End users have mini multimedia computers in their hands now. Someone is going to have to be involved in decisions around which devices best suit the environment and application needs,” Estes says.

2. Virtualization

No longer just a tool for systems administrators to tinker with in testing environments, virtualization technology is the main component behind data center consolidation and disaster recovery initiatives.
“Virtualization is a hot technology area, which means managers are looking for people with some savvy there,” says Steve Clifford, field recruiting director at staffing agency TAC Worldwide. “Many companies have a lot of redundant servers, and they are trying to maximize resources and utilization on every server on every site.”
And while server virtualization is the current hot technology, industry watchers expect storage, network and desktop virtualization to continue to drive demand for expertise in this technology area. EMA Research Director Andi Mann says desktop virtualization will show the strongest growth of any virtualization technology during the next one to two years.

3. Security

Security as a must-have skill is a nobrainer. A CompTIA skills survey released in February had security listed as the No. 1 skill among three-quarters of the 3,578 IT hiring managers polled. Foote Partners reports that security skills accounted for 17% of base pay in the fourth quarter of 2007, and pay for network security management skills increased by more than 27% in 2007.
But going forward, IT professionals will need to be able to incorporate their security savvy into network, wireless, application, operating system and other IT areas to best compete. “Firewall, data leak, compliance – you name it and it’s in demand for security,” says CompTIA’s Hopkins. “In the networking field, you need to also be an expert at security, but going forward skills around how to train staff and employees to be security- aware will have to be developed.”

4. Neworking

Networking expertise, which fell out of favor after the dot-com bust, is now back in demand and second only to security in terms of needed skills among the IT managers surveyed by CompTIA.
“Networking and infrastructure skills are back. Companies are not getting rid of data and they are doing more transactions online. With the growth and complexity of networks, there is a push for skills to design and manage such large-scale environments,” says Beyond.com’s Milgram. Martin Webb, manager of data network operations for the Ministry of Labour and Citizens’ Services in the province of British Columbia, says he is looking for people with practical experience in large enterprise IP-based networks, “both in terms of implementing services as well as operational support.”
“Experience in wide-area networking is hard to come by, particularly as it applies to traditional carrier networking technologies such as T-1, frame relay, ISDN and multiplexing,” Webb explains. “Today’s technical staff also need to have basic business
analysis skills with an understanding of financial management.”
Brian Jones, manager of network engineering at Virginia Polytechnic Institute and State University’s Tech’s Communications Network Services unit in Blacksburg, says he is always on the lookout for “field personnel who are well-organized. This means people who are experienced in installing networks, including everything from assembling racks to installing fiber panels, cross connect fields, cable management, and various network chassis and equipment.” Other networking skills he says are must-haves include proficiency in cable and fiber termination and splicing as well as experience installing and configuring edge switches. “These skills are hard to find and keep,” Jones says.
For John Tuman, director of network services at WakeMed Health & Hospitals in Raleigh, N.C., finding VoIP skills is a challenge. “There is a lot of talent available
with the traditional PBX, far less that have practical VoIP experience,” he says.
Virginia Tech’s Jones agrees. He says expertise in VoIP will only be more in demand
as time goes on. “VoIP, IPv6, and other emerging technologies will be driven by new applications and user requirements. IT staffers as always will have to learn these new things while maintaining the older technologies and services,” Jones says.

5. Application delivery

Often as networks become more complex and sophisticated, they also get distributed
over various remote locations and branch offices — which Gartner says is driving the
need for expertise in the area of application delivery.Application delivery networks, according to Gartner, are required if companies want to deploy modern browser-based
applications and emerging Web services applications. This network overlay responsible
for application delivery will demand skills that cross storage, security, network and application development disciplines. Knowledge of application optimization techniques such as protocol offload, caching, application firewalls and others would be required of application delivery experts on staff.
“IT departments that add these positions will see smoother application development and deployment, increased user satisfaction and lower costs,” says Joe Skorupa, research vice president at Gartner.

6. Web 2.0

Companies looking to implement Web 2.0 technologies want to see IT professionals with skills in areas such as AJAX, .Net and XML. These technologies require updated application development skills because they provide a more interactive experience, which could cause bandwidth or performance issues if not executed properly.
“For application development tools, AJAX, .Net, WebSphere and others have replaced and are replacing all the earlygeneration stuff like CGI, Visual Interdev and HTML/DHTML,” says David Foote, CEO and chief research officer at Foote
Partners.

7. IT business analysis

Being able to gauge the business relevance of technology decisions is critical for all high-tech hires, industry watchers and IT managers agree.
Arun DeSouza, a director of strategic planning and security at Inergy Automotive Systems in Troy, Mich., says skills around managing IT with finance in mind are in demand at his company. “Ultimately, all technology investments and operational expenditures are about enabling the business and adding to the bottom line,” he says. “IT managers need to be able to help align with the business, manage the financial portfolio and articulate the benefits in a language that the business can understand.”
IT managers expect their employees not only to have a comprehensive understanding of the business they support but also to keep that knowledge current. “The more senior a technical staffer gets, the more business aware they need to be,” says John Turner, director of networks and systems at Brandeis University in Waltham, Mass.

8. Database management

Database management skills are growing in importance, according to several industry sources. Robert Half Technology found database management to be considered an in-demand skill among 66% of 1,400 CIOs it polled. Foote Partners reported that median pay for database skills increased by 10% over the last two years, with Oracle database skills specifically seeing a 24% spike in pay over the previous 12 months. “Simply speaking, it is cheaper now to store data so more companies are keeping more data on large-scale disk drives, because in the online world content is king,” Beyond.com’s Milgram says. “The more content you have the bigger you are, and back-end SQL, MySQL and Oracle skills are in demand to ensure companies are successful at such large-scale data management.”

9. Business intelligence/data mining

In a similar vein as data management, business intelligence and data mining skills are growing in importance to enterprise companies as analyzing the data stored can directly impact a business’ bottom line. “Customers have spent so much money on gathering their data and putting it in data warehouses that they are now looking for ways to generate revenue from the data or from the knowledge contained within it,” says TAC Worldwide’s Clifford. “It’s important that IT professionals have these skills — one part business intelligence and one part data mining – but also that they can apply them in such a way that is suitable to their business. According to Foote Partners, pay for business intelligence grew by more than 22% in 2007.

10. The X factor

The trend is for IT professionals to emerge from being specialists in one technology area to being team members with broad knowledge of the environment. As networks and systems grow more sophisticated and intertwined with each other and the business, IT staff is expected to be well-versed in many areas and able to apply that know-how to the business at hand.
“I am seeing a need for IT staff to have a more holistic view when designing, integrating and troubleshooting. In the past, skill sets could be quite focused because there were better-defined lines of demarcation between systems; the trend continues to move to more interdependent and intertwined systems,” says WakeMed Health & Hospitals’ Tuman. “Now we need folks to understand how multiple systems interoperate, and when troubleshooting, have the ability to associate symptoms that surface in other areas back to the source.”
