LinuxSecurity.com Feature Extras:
Linux File & Directory Permissions Mistakes - One common mistake Linux administrators make is having file and directory permissions that are far too liberal and allow access beyond that which is needed for proper system operations. A full explanation of unix file permissions is beyond the scope of this article, so I'll assume you are familiar with the usage of such tools as chmod, chown, and chgrp. If you'd like a refresher, one is available right here on linuxsecurity.com.
Introduction: Buffer Overflow Vulnerabilities - Buffer overflows are a leading type of security vulnerability. This paper explains what a buffer overflow is, how it can be exploited, and what countermeasures can be taken to prevent the use of buffer overflow vulnerabilities.
Getting to Know Linux Security: File Permissions - Welcome to the first tutorial in the 'Getting to Know Linux Security' series. The topic explored is Linux file permissions. It offers an easy to follow explanation of how to read permissions, and how to set them using chmod. This guide is intended for users new to Linux security, therefore very simple.
Bulletproof Virus Protection - Protect your network from costly security breaches with Guardian Digital’s multi-faceted security applications. More then just an email firewall, on demand and scheduled scanning detects and disinfects viruses found on the network. Click to find out more!

| How to keep instant messaging off the record | ||
13th, October, 2005
Sometimes encryption isn't enough to keep your conversations private. With standard encryption, it's theoretically possible for someone to steal your secret encryption keys and decipher the conversation. For conversations that need to be kept confidential, the Off-the-Record (OTR) plugin for Gaim saves the day. It leaves no trace of a conversation ever having taken place. |

| What Are Digital Vaults? | ||
11th, October, 2005
A major challenge that is faced by all organisations selecting IT technology is trying to clearly understand how a particular solution may address the challenges they are tasked with solving. And this often involves trying to understand what various vendors mean when using generic terminology. |

| Insider Security Threats Q&A | ||
12th, October, 2005

| Playing Nice With Physical Security | ||
10th, October, 2005
At a small company, the information security manager is sometimes also responsible for physical security. At very large corporations, the physical security - sometimes called safety and security - is a completely separate department, responsible for hardware such as biometric ID or badge systems, security cameras and the management of guards. Safety and security departments handle investigations of physical breaches, such as theft, and workplace violence. |

| Perform due diligence with RFID security | ||
12th, October, 2005
Most notably, EPCglobal Gen 2 standards currently lack over-the-air data-stream encryption between passive RFID tags and readers, though there are provisions for locking RFID tag memory and disabling tags. EPCglobal Gen 2 is the current standard for how passive tags affixed to items and encoded with information about them communicate wirelessly with readers, which collect that information and pass it to upstream applications. |

| Developers 'should be liable' for security holes | ||
12th, October, 2005
Security expert Howard Schmidt wants coders to be held responsible for vulnerabilities in their code, but others say their employers should be held to account |
||
| I get a right good fisking | ||
13th, October, 2005
On a technical level it's wrong to call this a fisk. More like a right good padding. But I wasn't writing on a technical level. I was writing from a business perspective. Is Windows inherently less secure than Linux, or just more popular? Presently available data is inconclusive, because Windows still holds the bulk of consumer and small business market share. |

| Government must push on IT security | ||
14th, October, 2005
IT security has matured significantly over the past few years. An increase in the number of viruses such as Slammer, the advent of phishing, and a spate of high-profile attacks on organisations such as Sumitomo Bank, have pushed security to the top of many company agendas. While such publicity is scaring people into action, security still has a long way to go before it is embedded in everyday life. |

| Hacking for Dollars | ||
11th, October, 2005
Threats to information security come in all shapes and sizes, and from all directions: blended threats, mass-mailer worms, Trojans, phishing attacks, spyware, keystroke loggers, etc. Every day, one or more of these threats put critical information at risk in Internet-connected corporations and businesses around the globe. |
