Nmap Overview: A Leading Tool for Network Auditing and Scanning

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Nmap ("Network Mapper") is a free utility for network exploration and security auditing. It was designed to rapidly scan large networks, although it works fine against single hosts. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. Nmap runs on most types of computers and both console and graphical versions are available. Nmap is free software, available with full source code under the terms of the GNU GPL.

Unlocking Security Testing Speed With Chaos Linux Distribution

Chaos, a Linux distribution developed by Australian Ian Latter, harnesses the unused processing power of networked PCs, creating a distributed supercomputer that can crack passwords at lightning speed. The program remotely boots Linux on a PC without touching the hard drive, leaving the "slave" PC's operating system and data secure and untouched. Thirty PCs connected as a cluster create enough processing power to complete complex mathematical equations or high-level security tasks like password cracking that no individual PC could handle alone.

Analyzing Firefox Security Challenges in Multiuser Linux Environments

Is Firefox a more secure web browser than Microsoft's Internet Explorer? The answer may be yes, but the issues are more complicated than most people realize. In fact, Firefox has its share of security problems, and has probably been saved from real-world attack so far only by its single-digit market share,

NSA Security Enhanced Linux: Improving Cybersecurity Adoption Challenges

The National Security Agency built a version of Linux with more security tools that its technologists believe could help make the country's computing infrastructure less vulnerable. They've won over the Linux developer community with the changes. But success depends on its adoption by U.S. companies and government agencies, something that remains very much in doubt.

Honeynet Report Highlights Increased Lifespan Of Unpatched Linux Systems

Unpatched Linux systems are lasting longer on the internet before being compromised, according to a study by the Honeynet Project, a nonprofit group of security professionals that researches online attackers' methods and motives. Data from 12 honeynets showed that the average "life expectancy" of an unpatched Linux system has increased to three months from 72 hours two years ago.

Arkeia Backup Agent Remote Access: Buffer Overflow Exploit Analysis

On February 18th, 2005 "John Doe" posted a remote buffer overflow exploit for the Arkeia Network Backup Client. This vulnerability affected all known versions of the software, going back as far as the 4.2 series (when the company was called Knox). The buffer overflow occurs when a large data section is sent with a packet marked as type 77. The Arkeia Network Backup Client is your typical backup agent; it runs with the highest privileges available (root or LocalSystem) and waits for a connection from the backup server. The Arkeia client and server both use TCP port 617 for communication. According to the SANS ISC, the kids are wasting no time.

IBM Assessment of Open Source Security Tools for Linux Systems

To test open source security products, a study was conducted over a period of three months at the IBM Linux Test Integration Center. The goal for the security study was to deploy and compare various open source security tools that were available for free in the industry, and provide solution recommendations.v

Projected Demand for Security Skills and Linux Jobs in 2005

Security, Web services and Linux jobs continue to dominate the IT help wanted ads and are projected to remain among the hottest skill and certification areas in 2005, according to research firms that specialize in tracking skills and certifications. Researchers said companies continue to invest in security-related projects while looking to eliminate aging legacy systems, and are exploring less expensive, newer platforms such as Linux.

Honeypot Study: Unpatched Linux Systems Remain Secure for Months

The average unpatched Linux system survives for months on the Internet before being hacked, a report recently issued by the Honeypot Project claims. The life expectancy of Linux has lengthened dramatically since 2001 and 2002, the project said, from a mere 72 hours two and three years ago to an average of three months today. Honeypot Project is a non-profit that, as its name suggests, connects vulnerable systems to the Internet in the hope of drawing attacks so that they can be studied. To figure out the lifespan of a Linux system, the group set up a dozen "honeynets" -- the project's term for a system that hosts numerous virtual honeypot machines -- in eight countries, then tracked the time it took for those machines to be compromised.

New Insights: Linux System Exploit Durability Expands To Three Months

New Honeynet Project KYE paper released "Know Your Enemy: Trends". This paper documents how the life expectancy of unpatched or vulnerable deployments of common Linux systems has increased from 3 days to 3 months. This is surprising based on the increase of malicious activity seen in the past 18 months.

Integrating SEM Technology With Current Management Infrastructure

Integrating SEM (security event management) technology with existing security and system management infrastructure can be a hair-raising experience. Security point products such as IDSes, anti-virus gateways, and vulnerability scanners tend to use proprietary formats for reporting, recording network events, and issuing alerts. . . .

IPsec Implementation In Linux Kernel 2.6: Securing VPN Communication

IPsec is an addition to IP protocol that allows authentication and encryption of IP datagrams. It is defined in detail in IETF RFCs 2401, RFC 2402, RFC 2406 and RFC 2407 (see Resources). IPsec can be used to secure a rather wide range of scenarios; one of its best-known usages is creating virtual private networks (VPNs). . . .
