If you’re considering a career in cyber security, it's a good idea to develop a firm understanding of the industry terminology as well as many of the cyber security tools and techniques that are used to defend networks, systems and data against cyberattacks, including:
Anti-malware is a type of software-based cyber security tool that prevents malware (malicious software) from infecting a computer and removes existing malware from devices and systems. There are 3 common types of anti-malware software, each with its own method for identifying and removing malware:
Anti-virus software is another one of the tools for cyber security that many computer users are likely to be familiar with. It’s generally recommended that everyone install some sort of anti-virus software on their devices to keep dangerous software from infecting it.
Currently, the most powerful anti-virus software is called “next-gen software.” It has been in use since 2014 and is known by a shift toward signature-less detection. This type of anti-virus software may implement machine learning such as artificial intelligence, behavioral detection and cloud-based file detonation into its programming.
Cyber security professionals need to keep up to date on the latest developments in anti-virus software to protect the companies they work for. Because viruses are constantly evolving, it’s essential that companies are aware of the most effective, cutting-edge anti-virus technology and make upgrades to existing software when it becomes available.
Once completed, the ethical hacker compiles a report on how they were able to break into the system. The network administrator or cyber security professionals at the company who owns the network will then use this information to bolster the network's defenses.
Penetration testers typically use cyber security tools like Kali Linux, an open-source Linux distribution, as well as Metasploit, Intruder and Core Impact.
A packet sniffer, also known as a packet analyzer, protocol analyzer or network analyzer, is a hardware or software tool used to monitor network traffic.
Cyber security professionals use a combination of both hardware and software to build security. While a good portion of their work does include the use of cyber security tools like anti-virus software or firewalls, using the correct type of hardware to build networks and infrastructure is important, too. Just as they make recommendations for new security software upgrades, a cyber security professional can recommend that a company upgrade its hardware if it’s incapable of supporting the software.
