bounds functionality checking to protect the buffer. Avoid using functions that do not check the buffer (for example, in the C language, replace gets() with fgets()). Use built-in protected languages or use special security programs in the language code to prevent buffer overflow vulnerabilities...
The first worm was created by Robert Morris in 1988. Though he didn’t intend for it to be a malicious creation, the Morris worm infected its host machines many times over in abuffer overflow attack, resulting in computer shutdowns andnearly rendering the Internet unusable. ...
A buffer overflow can occur inadvertently or when a malicious actor causes it. Athreat actorcan send carefully crafted input -- referred to asarbitrary code-- to a program. The program attempts to store the input in a buffer that isn't large enough for the input. If the excess data is ...

Security measures to prevent CSRF -- for example, frequent authentication requests -- may be met with user aggravation. Cryptographic tokens can be used to provide persistent authentication. Find out more about theanatomy of a CSRF attackand how to reduce risk. ...
This chapter explores basic network applications—the clients and servers running in user space that reside at the application layer. Because this layer is at the top of the stack, close to end users, you may find this material more accessible than the material in Chapter 9. Indeed, you inte...
Buffer overflow malware for example appends a small amount of malicious code to the end of a URL, web page, script, or network packet - which when received and run on the client computer causes damage. Buffer overflow attacks are one of the most common web-based attacks. They are hard to...

When 2FA is used, even if a password is compromised using a technique like spear phishing, it’s of no use to an attacker without the physical device held by the real user. Password management policies A prudent password management policy should take steps to prevent employees from using ...
Loaders often do this by triggering a buffer overflow. This is a common security exploit that lets hackers land their code in otherwise inaccessible areas of a computer’s memory. Rootkits come bundled with a “dropper” and a “loader” that work together to perform an attack. The cyber...
