I have a bit more to say about the subject. The SysAdmin, Audit, Network, Security (SANS) Institute recently offered the Webcast "Legal Liability For Information Security: Ask the Experts." If you didn't tune in, you missed some interesting perspectives. (For a rebroadcast of the SANS Webcast, visit the URL below. Register and follow the instructions to access the show in the archives.) http://www.sans.org/webcasts/042303.php In one segment of the Webcast, attorney Marc Zwillinger offered his opinions about how torts will soon affect companies based on their information security practices (or the lack thereof). Without getting into complicated legal interpretations, one can define a tort as basically damage, injury, or a wrongful act that occurs either willfully or through negligence. In the past, to get into trouble in the arena of information security, you typically had to either break the law or break or violate a contract. Legal experts now think we'll start to see litigants suing entities for torts civilly--and perhaps even prosecuting them criminally, depending on the circumstances. For example, if your company is aware that it runs an open mail relay, and a spammer uses your mail system to send email in a way that causes harm or damage to another entity, your company has effectively committed a tort and might be found liable in a court of law. In another example, if you don't properly secure private user or customer information and that information becomes compromised, you might be held liable for civil damages. In the United States, almost anyone can sue someone else for almost any reason. So staying out of court might become increasingly difficult in some security-related instances. The legal experts note several ways you can help prevent litigation regarding your information security. One of the key factors in determining liability is whether you've taken reasonable steps toward keeping your systems and information secure. Another factor is how you respond to security incidents. These factors will probably determine whether and how you're found liable in the event that someone brings a legal action against you or your company. How you handle those matters--which steps you've taken to keep information secure and how you respond to security incidents--might also affect whether you qualify for cyber-insurance. When asked which were the most important security-related steps to take, members of the legal panel recommended that you explicitly assign responsibilities for security matters, put those assignments in writing, and have the responsible parties sign them physically, digitally, or both. You should take appropriate action before something becomes a problem for your business. You must be aware of the different layers of law under which you operate (local, county, state, federal, international) and respond to requirements accordingly. Find a capable lawyer to help ensure you aren't caught off guard. Finally, be sure you assign access rights and responsibilities carefully, after assessing people's skill levels and their need for access relative to their specific tasks and your business needs. Doing so can help avoid liabilities stemming from negligence. Do the insurance and the legal industries seem poised to start steering the information security industry more directly toward what it must do and how to do it? Will a day come when people won't be able to connect to the Internet without a proper license and cyber-insurance of some sort? I hope such potential changes won't occur--at least until after the day that computer software and hardware vendors become legally liable for defective products. I think many people agree that, like automobiles, software and hardware should have both better "precautionary devices" and more knowledgeable "drivers." In any case, it's clear that your company's security practices must be stated, assigned, and carried out to keep your company out of court in case of a mishap. You should know which security elements will come into play when courts make decisions about liability and take steps to address those elements--not only to avoid litigation but also to protect your company, its customers, and you. ~~~~~~~~~~~~~~~~~~~~ ~~~~ SPONSOR: HP & MICROSOFT NETWORK STORAGE SOLUTIONS ROAD SHOW ~~~~ TIME IS RUNNING OUT TO CATCH OUR STORAGE ROAD SHOW!

Microsoft has released Security Bulletin MS03-015 (Cumulative Patch for Internet Explorer) to address these vulnerabilities and recommends that affected users immediately apply the appropriate patch mentioned in the bulletin. For more details about these problems as well as links to the bulletin visit our Web site. http://www.secadministrator.com/articles/index.cfm?articleid=38781 * MHTML ARBITRARY CODE EXECUTION IN MICROSOFT OUTLOOK EXPRESS Microsoft reported a vulnerability in Microsoft Outlook Express 6.0 and Outlook Express 5.5 that can result in the execution of arbitrary code on the vulnerable system. This vulnerability is a result of flaw in the Mime Encapsulation of Aggregate HTML (MHTML) URL Handler. To exploit this vulnerability, an attacker can construct a URL and either host it on a Web site or send it by email. In the Web-based scenario, when a user clicks the site-hosted URL, the attacker can then read or launch files already present on the local machine. Microsoft has released Security Bulletin MS03-014 (Cumulative Patch for Outlook Express) to address this vulnerability and recommends that affected users immediately apply the patch mentioned in the bulletin. http://www.secadministrator.com/articles/index.cfm?articleid=38780 * BUFFER OVERFLOW IN CISCO ACS FOR WINDOWS Cisco Secure ACS for Windows contains a buffer-overflow condition that can permit a Denial of Service (DoS) attack and a root compromise. The problem appears to lie in the software's handling of logon sequences. Cisco Systems recommends that customers either upgrade to repaired versions of Cisco Secure ACS or install Cisco Secure ACS so that it denies or restricts access to management interfaces. Users who want to restrict access to management interfaces need to block access to ACS on port 2002. Cisco has released a bulletin and free upgrades, which you can download from the company's Web site. http://www.secadministrator.com/articles/index.cfm?articleid=38778 3. ==== ANNOUNCEMENTS ==== (brought to you by Windows & .NET Magazine and its partners) * GET ARMED WITH THE SAME SECURITY PROTECTION USED BY THE DEPARTMENT OF DEFENSE!

Detecting attacks on your network is crucial, but doing so is also difficult. That's where intrusion detection comes in. Intrusion detection is important, especially in a multilayered defense-in-depth strategy. To learn more about intrusion detection, read Jason Harper's article on our Web site. http://www.secadministrator.com/articles/index.cfm?articleid=24650 5. ==== INSTANT POLL ==== * RESULTS OF PREVIOUS POLL: WINDOWS SERVER 2003 The voting has closed in Windows & .NET Magazine's Security Administrator Channel nonscientific Instant Poll for the question, "Will your company upgrade to Windows Server 2003 for better security?"

Visit the site often to remain informed about the latest threats to your system security. http://www.secadministrator.com/panda * FAQ: HOW CAN I AUDIT USERS WHO START AND STOP SERVICES? (contributed by Randy Franklin Smith, rsmithat_private) A: Like files and folders, services are access-controlled objects, and every access-controlled object has a security descriptor. Part of a service's security descriptor is the system ACL (SACL), which you can use to track access to that object. The only way to view or change a service's current SACL is through security templates. To reach the security templates, log on to the server and open the Microsoft Management Console (MMC) Security Templates snap-in. To create a new template, right-click the security templates path. Select New Template, click System Services, then double-click the appropriate service (e.g., Telnet). Select the "Define this policy setting in the template" check box, then click Edit Security to open the Security for Telnet dialog box. This dialog box contains the service's ACL, which you can use to fine-tune who has start and stop authority.

(Three messages in this thread) A user wants to let his five remote users access the company network from the users' ISP dial-up connections in various states around the country. The users could then use Microsoft Outlook natively to manage such functions as correspondence and contacts. His network uses a Cisco Systems PIX Firewall, and he needs some guidance on how to implement a VPN tunneling solution on the firewall. He wants to know whether he can simply install the Cisco VPN client software on the remote users' machines or whether the firewall will need some special configuration also.
