Organizations using Microsoft's Defender for Endpoint will now be able to isolate Linux devices from their networks to contain intrusions and whatnot. . The device isolation capability is in public preview and mirrors what the product already does for Windows systems. "Some attack scenarios may require you to isolate a device from the network," Microsoft wrote in a blog post . "This action can help prevent the attacker from controlling the compromised device and performing further activities such as data exfiltration and lateral movement. Just like in Windows devices, this device isolation feature." Intruders won't be able to connect to the device or run operations like assuming unauthorized control of the system or stealing sensitive data, Microsoft claims.

IBM last week introduced technology called FairUCE, for Fair Use of Unsolicited Commercial E-mail, that blocks spam by trying to ID the sender's Internet domain rather than evaluating message content. . FairUCE aims to stop spam at the perimeter, before it becomes a burden to business networks, says Marc Goubert, manager of IBM's alphaWorks, a Web site for downloading emerging technology. FairUCE sends a query that, if an E-mail's domain is spoofed, must be answered before the message is delivered. That puts a challenge's labor and bandwidth burdens only on those marked as spammers. But identifying spammers is an inexact science. "A lot of spam these days comes from hacked machines," says Bruce Schneier, founder and chief technology officer of Counterpane Internet Security Inc.

Similar to packet sniffing, port scanning and other "security tools", vulnerability scanning can help you to secure your own network or it can be used by the bad guys to identify weaknesses in your system to mount an attack against. The idea is for you to use these tools to identify and fix these weaknesses before the bad guys use them against you. . . .. Similar to packet sniffing, port scanning and other "security tools", vulnerability scanning can help you to secure your own network or it can be used by the bad guys to identify weaknesses in your system to mount an attack against. The idea is for you to use these tools to identify and fix these weaknesses before the bad guys use them against you. The goal of running a vulnerability scanner is to identify devices on your network that are open to known vulnerabilities. Different scanners accomplish this goal through different means. Some work better than others. The link for this article located at NetSecurity.About.com is no longer available. . Vulnerability scanning is essential for network security, detecting weaknesses that could be exploited by attackers through automated tools and assessments.
