HOW-TO: Software Security
|
A framework for considering security in embedded systems
The need for security in many embedded systems is not always readily apparent, and too many embedded systems designers are paying too little attention to the subject, despite the increased wired and wireless connectivity of such designs.
Calculating the exploitability of your embedded software
To help developers get a feel for the factors that might affect the exploitability of their embedded system device, Eric Uner has some tips on a 'back of the napkin' way to get a sense of an application's vulnerabilities by showing it mathematically.
Embedded tools train an eye on security
One of the most important trends affecting embedded-systems design is the need for security and safety, as highlighted by the events of 9/11 and the continuing vulnerability of cyberspace. As embedded designers incorporate more security and safety needs into devices, embedded tools will have to evolve to provide capabilities needed both for product development and process management.
Need for server-level protection heightens
Much has been written about perimeter security using tools like firewalls, virus walls, intrusion detection, VPNs (Virtual Private networks), and DMZs (De-militarized Zones) as frontline defense.
Definitions and Value of Honeypots
Over the past several years there has been a growing interest in honeypots and honeypot related technologies. Lance Spitzner discusses what honeypots are, how they can add value to an organization, and several honeypot solutions. There are a variety of misconceptions on what a honeypot is, how it works, and how it adds value.
Intrusion Detection Systems
Whenever a company connects its network to the Internet, it opens up a whole can of worms regarding security. Many companies deploy a firewall, but to protect an organization completely, it is necessary to provide a second line of defense—Intrusion Detection Systems (IDS). The NSS Group's Bob Walder introduces this category of security software.

Internet Commerce
"Is my Internet transaction safe?" We all know that the Internet is not a tamper-proof secure channel, but a number of products and technologies significantly reduce consumer risk. The NSS Group's Bob Walder introduces encryption, digital signatures, and certificates.
