Top Layer Networks' Attack Mitigator lies at the traditional end of intrusion prevention. It aims to defend against both internal and external hackers using denial-of- service (DoS) and distributed denial-of-service (DDoS), as well as giving broad protection against other well-known attacks. This is done using a mixture of stateful inspection hardware and packet inspection software.

SonicWALL is well known for its firewalls, but it is now starting to add optional functionality to the range. The model tested came with the extra-cost items of content filtering and anti-virus. Vulnerability assessment is another optional extra, but was not supplied on the review unit.

Flaws in data back-up products were among the software problems cited as most serious in a quarterly update of the SANS top 20 most critical vulnerabilities released Monday. Federal agencies have not secured their wireless networks, despite well-known risks associated with WLANs, according to a report by the Government Accountability Office.

McAfee is well known for anti-virus software, and has built its complete anti-virus engine into an internet gateway product that examines HTTP, FTP, SMTP and POP3 traffic for viruses. It also performs content filtering and acts as an email anti-relay. Within the content filtering mechanism anti-spam functionality is included.

The principle of Xiscan is a good one. It takes the idea of war dialing software, which hackers have used to their advantage for many years to scan telephone networks in an attempt to locate entry points, and turns it against the enemy.
Xiscan works in the same way that the hackers have always used automated telephone dialers – to probe for weaknesses in the network. The difference is that it is designed to be used within the network, to locate rogue modems and bring users to heel.
The basic idea is that if hackers can use automated dialers to gain an advantage over legitimate users, then why can't the legitimate user do the same? It is a very good question – and there is something very satisfying about the idea of wrestling control of hacker-type tools, and using them for legitimate ends. Xiscan takes the wardialer idea and turns it on its head, using it as a way to monitor the network from within.

This solution provides a network-based IDS, real-time session monitoring and internet/email content blocking. eTrust Intrusion Detection can be installed in standalone mode, or it can be distributed on separate machines. The intrusion detection program installs as a service under Windows NT/2000. As usual, the monitoring interface is a NIC in promiscuous mode, and therefore the presence of the IDS is concealed from the attacker.

Four out of five inbound emails are designed to deceive the recipient, according to a new report studying the scope of abusive online messages. Virus authors appear to have gone on holiday, according to a new report. Weaknesses in information security policies and practices at 24 federal agencies put federal information and data systems at risk, according to a report by the Government Accountability Office. Starting Wednesday, businesses that have consumer report data must ensure that their methods for discarding such information adhere to certain guidelines. Networks of compromised PCs or botnets are fast becoming the weapon of choice for organized gangs to launch phishing attacks, according to a new report. Most insider attacks are planned well in advance by former employees intent on revenge, according to a study released by the U.S. Secret Service and the Carnegie Mellon Software Engineering Institute's CERT.

Although F-Secure may not be the first name in anti-virus that springs to mind, its products are among the heaviest hitters in the industry. Unlike some products which depend purely on their signature lists to be updated, F-Secure also comprises multiple scanning engines and heuristic detection techniques that make it one of the first products to detect new viruses. The company has now brought its expertise to bear in email security with F-Secure Anti-Virus for Internet Mail.

The product is available for Windows (NT and 2000). A Unix version would be nice, although there is a version for Unix which sits at the firewall level. Installation presented no headaches. However because of the way the product works, disk and memory requirements are quite high. It is also better to share the scanning across more than one scanner server to keep bandwidth usage lower.

Hackers are increasingly taking aim at vulnerabilities in security products rather than operating systems, according to a new report. Phishers are targeting smaller organisations to maximise profit and fool even the net savvy, the latest report from the Anti-phishing Working Group (APWG) shows. The Department of Homeland Security still has a lot of work to do in order to meet its cybersecurity duties, according to a report by the Government Accountability Office. Federal agencies need to do more when it comes to ensuring the security of contractors providing IT services and systems, according a report by the Government Accountability Office. The Federal Deposit Insurance Corporation (FDIC) still needs to shore up its sensitive computer systems, despite making significant improvements to its infosec efforts, according to a report by the Government Accountability Office. Chinese phishing websites have rocketed in the last year, with 223 reported in 2004 according to a new report.
