Security Action Plans

Centralization, automation, problem prioritization--many IT-security professionals are embracing those concepts as they fight off the never-ending onslaught of threats. Security products can help businesses stem the flood of vulnerabilities, but IT teams also have to put in place processes to ensure that they're responding appropriately and being proactive in warding off potential dangers. Fact is, some companies spend too much on some parts of their organization and not enough on more-vulnerable areas.
Security pros are under increasing pressure to do the job right and cost-effectively as networks extend beyond firewalls to remote users, partners, and customers, and to cell phones, PDAs, and other mobile devices; regulatory requirements to safeguard data have risen; and concerns about identity theft are at an all-time high. Hackings and other unauthorized access contribute to the approximately 10 million instances of identity theft each year in this country, according to the Federal Trade Commission. "How sensitive is a company about being on the front page of the paper?" asks Pete Lindstrom, founder and analyst at Spire Security. InformationWeek and others have reported on a rash of cases involving inadequate security and poor handling of customer data. "If the value of assets is high, companies should follow security best practices," Lindstrom says.
To understand how companies are managing it all, InformationWeek interviewed business-technology professionals on the front lines to see how they're handling some common security issues. From the higher-level picture of risk management to the nitty-gritty details of patching, here's how they do it.
Start With A Master Plan
For many businesses, implementing a risk-management plan should be at the top of their security to-do list, says Jon Oltsik, an analyst at Enterprise Strategy Group. But few have taken that step, he says. Instead, the most common reaction to a new threat is to buy more technology. "It's like you're sick, but you just buy medicine instead of going to the doctor," he says.
"With vulnerability assessment before, we'd sift through hundreds of pages for the E-commerce server or the print server," Hoff says. "Now Qualys shows us where we're vulnerable in business terms." For example, when Microsoft issues patches for its Windows operating system, the credit union uses Qualys VM to identify the first servers to patch. Other security risk-management vendors include Consul, eEye Digital Security, and Trusecure.
It all adds up to the need to deploy smart identity-management tools and establish savvy practices. At Vitas Healthcare Corp., with a workforce of 6,000 and operations across 15 states, authorized employees enter as many as a half-dozen passwords a day to access multiple databases. While it's important to maintain password discipline to secure customers' health-care data, maintaining and managing the situation creates a drag on the IT department. "Our help desk spends 30% of their time on password management and provisioning," says John Sandbrook, senior IT director at Vitas. The company is changing that using Fischer International Corp.'s Fischer Identity Management Suite 2.0 to manage passwords and comply with data-access regulations such as the Sarbanes-Oxley Act. Vitas implemented the suite last fall, and it expects to cut help-desk time spent on passwords by 25%.
The ID-management product includes automated audit, reporting, and compliance capabilities, and a common platform for password management, provisioning, and self-service. "Any company must have unique user IDs and passwords that change frequently," Sandbrook says. With the software, Vitas can enforce strong passwords that some legacy systems won't require on their own, such as those with seven, eight, or nine characters, numbers, and capital letters. And when Sandbrook does an audit, "I see who changed [password] information with good practices, and I feel assured."
Centralize To Survive
To counter spyware, spam, viruses, and unauthorized network intrusions, companies must consolidate and automate. Sounds simple, but many companies still are recent converts to those practices.
For HNTB Corp., a large architectural and engineering firm, moving to an antivirus product with a central console to manage and impose security policies and monitor employees' system usage has dramatically improved the company's security performance. "We haven't had a major outbreak since we put this in place" nine months ago, information manager Travis O'Dell says. In fact, there have been no outbreaks of any kind. Previously, the company saw two or three over the same time period.
They do at the AAA Reading-Berks office in Pennsylvania. The auto club's IT director, Peter Wallace, attacks spyware and viruses--which often enter a network as spam--in the same manner, by letting automated tools spot and fix problems. When spyware entered the vernacular, Wallace drew on his experience dealing with viruses to help shape his approach. A server in his office goes out and checks for updates to Computer Associates' eTrust Antivirus software. "I pull up the console, see how many machines are online, and update them as needed," he says. The number of viruses infecting systems has shrunk. "I just know I can sleep better at night because my server is updating in the middle of the night," he says.
The onslaught of spyware fractured some of that hard-won control over potential security holes. Wallace was spending most of his time last fall trying to keep spyware off the PCs that the auto club's 95 employees use. It slowed systems to a crawl and required Wallace and his single IT staffer to wipe machines clean, reload operating systems and applications, and reset user access rights. "The biggest pain was seeing a clean machine that was fine for a month, but then experiencing problems again," he says. During a bad week, the two-person team spent about 40 hours cleaning infected machines.
Since deploying CA's Pest Patrol, Wallace has cut the time he spends on spyware to 15 minutes a week. The software detects and removes spyware, so Wallace no longer has to pull customer-service agents' systems offline to fix problems. The greatest benefit is the impact on operations: fewer outages and fewer people needing to move off their systems while working with customers, Wallace says. Other vendors with spyware-fighting products include InterMute, Microsoft, and Webroot. Symantec also offers anti-spyware software, along with antivirus and anti-spam products.
Staff training and the support of company management are crucial in fighting all these threats, analyst Oltsik says. Employees need to understand what spyware is and how to avoid it. "Users and the help desk should know what to do when a PC gets flaky, and the training should be consistent and related to benefits," he says. "Any of these efforts need to involve the whole company."
Patch Tuesday didn't used to be pleasant at OMD, a media buying and planning subsidiary of Omnicom Group Inc., network administrator Ryan Hudson says. "Before, we did patches manually. We'd have to upgrade a critical patch on all 100 servers, and it took more than a week to get to them all," he says. OMD tested patches before deployment, loading them onto a test LAN before installing them on live machines.
For Hudson, the new patching policies and technology have made Patch Tuesday much easier. "I don't have to think about patch management now," he says.
Given everything else that security pros do need to think about, that's a welcome relief.
