Creating a Cyberdefense

E-Strategies Worried that terrorists might attack U.S. computer systems next? A few simple precautions will go a long way toward protecting your company. Even before last September’s terrorist attacks, the law firm of Lewis and Roca LLP was hypercautious about safeguarding its sensitive digital documents. In fact, compared with other small companies in the law firm’s home city of Phoenix and other law firms nationwide, Lewis and Roca seemed not just security-conscious but, well, a tad security-paranoid. For instance, accessing the firm’s sophisticated client extranet had always required using a tool that constantly generated new personal-access numbers. And the firm’s network automatically logged off users whose keyboards were idle for more than 60 minutes. But that was before September 11. Afterward, like their counterparts at other businesses nationwide, Lewis and Roca executives worried even more about the possibility of unseen intruders infiltrating their computer systems. So the 51-year-old firm, which also maintains branch offices in Tucson and Las Vegas, immediately had an in-house team focus more closely on reviewing the firm’s entire data-protection arsenal. The law firm’s biggest priority, of course, is protecting the physical safety of its 350 employees, says chief operating officer Robert S. McCormick. To that end, Lewis and Roca has increased surveillance and security in all its buildings. But shielding its confidential records from theft, damage, or deletion also remains what McCormick calls a top “ethical and legal responsibility.” Lewis and Roca is far from alone in reconsidering its whole spectrum of data security. And under the circumstances, the firm is hardly overreacting. “Right now I don’t think it’s possible to be too worried” about safeguarding records, says Weston Nicolls, a former National Security Agency executive who is chief information security officer at Telenisus Corp., a provider of managed Internet infrastructure services based in Chicago. Nicolls’s concerns are shared by Michael A. Vatis, director of the Institute for Security Technology Studies at Dartmouth College. In a report released just after September 11, Vatis warned that attacks on U.S. computers were “extremely likely” as part of larger, coordinated terrorist actions launched in retaliation for U.S. military strikes. Federal officials apparently agree. Three days after the September terrorist attacks, the FBI’s National Infrastructure Protection Center issued a formal advisory warning of possible vigilante activity online. A few weeks later, the Bush administration appointed longtime White House counterterrorism coordinator Richard Clarke to the newly created job of cyberspace security adviser. Clarke has repeatedly warned Congress and U.S. businesses about the potential for a “digital Pearl Harbor” in which distant assailants would invade and damage the country’s computer networks and telecommunications systems. The good news is that there were no reports of widespread cyberterrorism in the weeks immediately following the suicide hijackings. But as the Dartmouth report points out, previous political conflicts — for instance, clashes between India and Pakistan — have led to “cyberattacks” in those countries. So as U.S. military action continues overseas, Americans need to be highly alert for a possible new wave of virtual warfare, with both distant and domestic hackers trying to deface or crash Web sites, disseminate computer viruses, and break into vulnerable networks to steal, corrupt, or delete information. Osama bin Laden’s shadowy, computer-literate followers aren’t the only potential assailants. “Even more likely are cyberattacks by sympathizers of the terrorists, hackers with general anti-U.S. or anti-allied sentiments, and thrill seekers lacking any political motivation,” the Dartmouth report warns. In other words, companies should consider cyberterrorism not just possible but probable. They should also prepare accordingly, just as a California company might plan its response to an earthquake or a power failure and an East Coast business might protect its systems and data against a likely blizzard or hurricane. That means taking stock now to determine what’s sufficiently safeguarded and what’s still vulnerable — and having an IT staffer or outsourcer make corrections immediately. “Once you’re attacked is not the time to think about how to respond,” says Mark Schertler, vice-president of networking and security services at Primitive Logic Inc., a consulting firm in Sausalito, Calif. “You should have a recovery plan in place. You should have discrete and diverse service providers so that if one gets attacked, you can still operate. And if you’re relying on the Internet for revenue, you should have redundant sources to connect to it.” What’s the minimum computer protection for small businesses? For starters, virus-scanning programs. Self-installed software that detects and stops both viruses and worms can cost as little as $100. Once the software is installed, companies should assign someone to update the protection programs at least once a week — but preferably daily — to protect against the latest nasty attack. “It’s like an arms race,” says Schertler. “New viruses are coming out all the time.” A second must-have: a firewall, or shield, between the company’s internal systems and the Internet, to prevent unauthorized intrusions. The cost for that ranges from less than $50 for a home-based business to thousands of dollars for large companies with many remote users and massive amounts of confidential or valuable information. Next, companies of all sizes should regularly back up all systems. Small companies may be able to get by with weekly backups; businesses of, say, $10 million or more in annual revenues should invest in technology that will take a data snapshot daily. Both should stash the stored data off-site. (Nicolls of Telenisus suggests using a bank vault.) Every company should also make plans to run its networks from another location if necessary. Growing companies may also want to invest in a virtual private network (VPN), which provides far-flung employees, business partners, customers, and vendors with a secure tunnel into a business’s internal computer system. They should also add security software to their road warriors’ portable equipment, such as laptops and personal digital assistants. (See ” Laptop Insecurity,” Inc, March 15, 2001.) Users of Microsoft’s Windows operating system may want to consider upgrading to the new Windows XP operating system for its built-in firewall, enhanced virus protection, and capability for encrypting files both on the desktop and in transit over the Internet. For businesses of all sizes, Primitive Logic’s Schertler, who like Nicolls is a former NSA official, recommends two other security precautions that together cost precisely nothing. First, require employees to use “strong passwords,” made-up phrases that would-be intruders can’t guess or decipher, by running programs that automatically test passwords with common words or names. “Mix up letters and symbols to create something you wouldn’t find in a dictionary,” says Schertler, something like “drB613Jzx.” Second, assign someone on staff to act as your in-house point person for software-vendor updates. That way, your company will get regular reminders about such things as upgrades and patches, which crop up over time. Some security breaches, particularly those on Web sites, happen simply because nobody has the responsibility for retrieving the remedy for a security hole. Lewis and Roca already had many of those precautions in place. But after the terrorist attacks, the firm looked even harder for potential weak spots. Its in-house security team renewed its interest in how the firm controlled access to its systems, including its public Web site and client extranet. Team members also reviewed the firm’s virus-scanning capability, as well as its plans for preserving digital records during a natural — or terrorist-caused — disaster. In direct response to the World Trade Center attack, they even researched ways to salvage paper records. “The pictures of legal documents floating through the streets of lower Manhattan made us aware that recovery of electronic data alone may not be sufficient,” says chief operating officer McCormick. “We may want to consider technologies that will provide us with electronic images of our paper documents and files.” At the same time, the law firm, like many other small businesses, realizes its security-improvement process will never be finished. “It’s fluid, it’s evolving,” McCormick says. “We’re learning new things day by day as the situation changes.” In fact, on the day McCormick made those comments, his firm had just launched a new security initiative to investigate ways to monitor incoming mail for evidence of explosives, anthrax spores, or other potentially deadly materials. The firm also advised employees about ways to protect and preserve data on their own home computers, as well as ways to secure office E-mail and voice mail. Yet despite widespread concern about cyberterrorism, the FBI’s data indicate that most security problems originate within a company’s walls, either by accident or by design. For that reason, experts also recommend that companies monitor their networks for unauthorized remote access, set alarms to indicate large deletions of files, and remove ex-employees’ access to computer, E-mail, and even voice-mail systems as soon as they’re out the door. As security expert Nicolls puts it, “Unfortunately, people can still screw up the very best technology you can buy.” Anne Stuart is a senior writer at Inc.

Siamak Farah, CEO of InfoStreet, a $1.8-million developer of corporate intranets in Tarzana, Calif., wants his 15 staffers to take initiatives and run with them — as opposed to waiting for a manager’s approval. So in early 2000 he inaugurated “the 48-hour rule.” “If an employee comes up with an idea or proposal and submits it to his or her superior, the superior has two working days to respond,” he explains. If a manager doesn’t respond within 48 hours, then the employee can proceed under the assumption that the manager has granted approval. Farah says the rule has “done wonders” for decision making and initiative taking. And what if, perchance, a manager is away for two days? Nothing changes.

Protect Your Business From a Hack Attack

Safeguarding your Web site — especially sensitive site areas such as shopping cart software — against hackers need not be an expensive and time-consuming affair. With a few basic precautions, you can make your Web site extremely difficult and unrewarding to hack. Your Web site is most susceptible to hacking through your shopping cart, so choose wisely. Here are three guidelines to help you choose the best one for your business: Shop around. Use newsgroups such as AOL.com’s Search Newsgroups and online reports such as About.com’s Web Store Software Selector to verify the products you want to purchase are safe to use. Avoid free software. Although it might seem an attractive option, downloading free shopping carts is extremely risky for three reasons: the source of the software is indeterminate; you can’t check the creator’s credentials; you have no one to hold responsible for hacking incidents. Buy smart. Several ready-to-use shopping carts on the market today, including EasyCart, Monstercart.com, and MerchandiZer, have been designed specifically for the small, online business owner. These are often available at little or no cost. But be aware: No software comes with a no-hacking guarantee. There’s always a chance that a hidden access password, or backdoor, might be lurking. In 90 percent of all hacking cases, the most vital data had been provided from within the organization. Here are three rules to follow religiously: Change the default password immediately. Whenever you purchase a ready-to-use shopping cart, your first step should be to change the default password that comes built into the software. Although this might seem an obvious precaution, it’s one many people overlook. Change your shopping cart password frequently and guard it zealously. Change passwords often. Frequently change passwords. Tell relevant passwords only to those who truly need to use them. Use passwords that include letters and numbers, and don’t use a password that’s easy to guess. Never write your passwords on sticky notes and paste them to your desk or monitor. Restrict access to passwords. Never allow more than one person the use of your server access password. For example, the person in charge of packaging doesn’t need to know your file upload password. If an outside agency designed your Web site, ask for all access passwords and change them immediately. If any changes need to be made on your site, you provide the password and control access to your server at all times. Many small, online business owners maintain their central work database and their Web server on the same computer. While this seems convenient — and necessary for storing such information as product descriptions, prices and images — any machine connected to the Web is dangerously vulnerable to attack. Here are two ways you can thwart would-be hackers: Delete sensitive data from the Web server. Sensitive customer data, such as addresses and credit card information, should never remain on the Web server itself. Even if the server is protected by a password, this data is only a few keystrokes from a talented hacker. Instead, devise an automated system to periodically copy any data stored on your Web server to a machine located on your premises and then delete the data on the Web server. After the data has been copied to your off-line system, restrict access to that system as well. Send sensitive data securely. Although the chances of a hacker intercepting data while it’s being transmitted are very low, you can protect your customer’s most sensitive information by providing a secure connection between your customer’s browser and your server. If you host your Web site on your own server, two companies, VeriSign and Thawte Consulting, offer this security using technology called Secure Sockets Layer (SSL). These companies provide a downloadable device called a digital certificate to verify to your customers that your company is a bona fide business. If you don’t host your own site, ask your Web host to provide a secure connection. Your host probably has a relationship with an SSL provider. It will cost you only a little more and it’s worth it; SSL protects your data from hacking and serves as reassurance to your customers. Regularly and consistently tracking activity on your Web site will help identify hack attacks. Here are three ways to do it: Monitor server access. Ask your network administrator to install a remote access mechanism that lets you shut down your server remotely as soon as you find evidence of suspicious activity. This will stop any hacking activity in its tracks. Your network administrator should be able to install a real-time alert, such as a beeper alarm or an automatic e-mail message, to inform you of any unauthorized attempts to access your Web server. Monitor site traffic. Changes in site traffic patterns sometimes indicate a hacker at work. A noticeable dip in traffic could mean something’s wrong with your Web site and would require immediate attention. Be sure to monitor site traffic on a regular basis. Run extensive sitewide checks if you notice any inexplicable changes. Run “preflight” checks. Make it a point for you or one of your employees to check the functionality of the entire site, especially the shopping cart area, every day. Here’s a checklist: Check whether the site is accessible on the Web. Check whether the home page displays the correct data. Perform random price checks within the Web site. Check the help function to see whether any data has been altered. Click links in the site to make sure they link to the right pages. Test the results of your search functions. Add random products to your shopping cart and proceed to checkout. What if you still fall victim to a hacker’s attack? Develop an action plan to minimize further damage to your system and to avoid inadvertent destruction of evidence. Your plan should include: Clear delegation of tasks to specific employees in the case of a security breach. A contact list of your Internet service provider (ISP) and/or Web host, Web site designer, network administrators or any Web security contractors you might want to use to recover from an attack. A contact list of local and national authorities to inform of the incident, including the FBI’s 24-hour service for immediate guidance after the attack. Periodic tests of your emergency procedures. And remember: Firewalls and fancy measures notwithstanding, the big break for a hacker will most likely be one little, vulnerable password. Copyright © 1995-2000 Pinnacle WebWorkz Inc.

This Year’s Hacker Attacks

The online assaults began Monday, Feb. 8, 2000, blasting Yahoo! with more packet traffic (service requests) than most Web sites receive in a year. The site was down for three hours. On Tuesday, eBay, Amazon.com, Buy.com, and CNN.com were hit with the same type of attack. E*Trade Group and ZD were the victims on Wednesday. It took more than two months to catch the hacker — a 15-year-old Canadian boy who gave himself away by bragging about his exploits in hacker chat rooms. Here’s another true story: The FBI chose April 1 to announce a new virus, called 911, that attacks Internet service providers. Many wonder whether the virus alert is an April Fools’ joke. But the virus is real, earning its name by dropping code into your system that overwrites your computer’s hard drive and then uses your telecommunications software to dial 911. The virus leaves the computer useless and the local community emergency services swamped with false calls. And another: Two teenagers from Wales, posing as Curador: the saint of e-commerce, steal thousands of credit card numbers from various sites and use the information fraudulently to buy domain names so that they can post the information on the Internet. Their activities cause more than $3 million in losses. The sites were breached by a two-year-old hole in Microsoft’s Internet Information Server (IIS) software. Microsoft had created a patch for the hole in the IIS system in 1998 and reissued a warning in 1999. But small e-commerce sites don’t have the resources to maintain the security they need. It’s a War Out There Once you are connected to the Internet, your entire network of computers — not just your Web servers — becomes susceptible to malicious attack. To many IT professionals, protecting the network means waging an all-out war against anyone trying to breach their security measures. Small businesses must defend their computer systems against three potentially business-crippling attacks. These attacks can come from hackers (people who manipulate and bend program codes) and crackers (people who crack code for malicious reasons). These people aren’t always out to harm and steal from you, but what they’re doing poses a definite threat to your network. Copyright © 1995-1999 Pinnacle WebWorkz Inc. All rights reserved.

A Byte out of Cybercrime

With so much sensitive information streaming through the Internet, it’s no wonder that high-tech crime-fighting units are springing up all over the country to combat digital fraud, theft, and sabotage. Police sergeant Don Brister of the High Technology Crimes Detail in San Jose, Calif., investigates corporate espionage, among other offenses. Brister warns that with such crimes on the rise, companies should do more than build firewalls to protect their inner systems. They should also keep a sharp eye on what’s going on within the organization. Follow these few simple precautions, Brister says, and protect your company from digital mischief. Since most corporate computer crimes are committed by former and current employees, Brister suggests that companies sever their ties with bad employees immediately. Allowing a recently fired staffer to stick around for the standard two weeks allows that worker to gather all the information and security codes necessary for future hacking. “That’s the making of a disgruntled employee who can do a lot of damage,” Brister says. “Almost any employee can bring a business to its knees. Managers and owners should look at immediate dismissal as protecting the business early on, even if it means losing a few dollars by not having a person there.” Companies can prevent a lot of trouble, Brister says, if they conduct complete background checks on prospective hires. “We’ve been involved in many cases in which warehouse people, even people in the financial department, have had criminal records,” he says. “Even though that history is public, the company hasn’t known that it’s available or how important it is. And while many organizations would rather be kindhearted than suspicious, there are people who will go from company to company and continue stealing.” Brister says it’s important to call in the law at the first sign of trouble. Don’t wait until a series of crimes have occurred. Early reporting means that police can log the incidents and have more leads to follow. Even if there isn’t yet a high-tech-crime unit in your city, Brister says, state police departments often have forensic computer labs. And if state agencies aren’t able to help, Brister suggests calling the FBI, the Secret Service, the U.S. Customs Service, or even the post office.
