WHAT IS A WORM

What is a worm?

Along with “computer virus,” the term “computer worm” has become a highly familiar phrase thanks to the rapid rise and media coverage of cyber threats in recent years.

But what is a worm and what danger does it pose to your system or your organization? Here’s a brief primer on “What is a worm?” and what you can do to prevent them.

What is a worm?

So, what is a worm exactly? A worm is among the most common types of malware – a bit of computer code that is designed to cause harm to a host network by overloading servers or consuming bandwidth. Some computer worms may also include “payloads” that can damage systems, steal data or delete files.

What is a worm’s method of propagating?

While computer viruses are spread when users run a program or open a file, computer worms have the ability to spread automatically without human intervention. Worms can self-replicate, creating multiple versions of themselves to spread to other computers.

What is a worm’s greatest threat to a system?

A worm may be used to create a backdoor that allows the host system to be controlled by other computers and used to spread spam or perform denial-of-service attacks.

What is a worm security test?

In addition to anti-virus protection, security testing is critical to preventing worms. Application security tests can identify vulnerabilities like cross-site scripting or buffer overflow that may allow attackers to access a system and initiate a worm.
