Network Threat
Sample Solution
Three network threats and the IT infrastructure domain that the threat may harm:
- Malware: Malware is malicious software that can damage or disable computer systems and networks. Malware can be delivered in a variety of ways, such as through email attachments, malicious websites, and USB drives.
IT infrastructure domain that the threat may harm: All domains
Why/How: Malware can damage or disable any IT infrastructure domain, including the user domain, workstation domain, LAN domain, LAN-to-WAN domain, remote access domain, WAN domain, and system/application domain. For example, malware can encrypt files, steal data, or disrupt network operations.
Full Answer Section
- Phishing: Phishing is a type of social engineering attack that attempts to trick users into revealing confidential information, such as passwords and credit card numbers. Phishing attacks are often carried out through email, but they can also be carried out through phone calls, text messages, and social media.
IT infrastructure domain that the threat may harm: User domain
Why/How: Phishing attacks are targeted at users, so the user domain is the most at risk. If a user falls for a phishing attack, the attacker may be able to gain access to the user's account and steal data or launch further attacks.
- Denial-of-service (DoS) attacks: DoS attacks are attempts to make a computer system or network unavailable to its intended users. DoS attacks can be carried out by flooding a system with traffic or by exploiting vulnerabilities in the system's software.
IT infrastructure domain that the threat may harm: All domains
Why/How: DoS attacks can target any IT infrastructure domain, but they are most commonly targeted at the LAN domain and the WAN domain. If a DoS attack is successful, it can prevent users from accessing critical systems and resources.
How to protect against network threats:
There are a number of things that organizations can do to protect against network threats, including:
- Educate users about security best practices. Users should be educated about the different types of network threats and how to avoid them. This includes training on how to identify phishing emails, how to create strong passwords, and how to avoid clicking on malicious links.
- Implement security solutions. Organizations should implement security solutions such as firewalls, intrusion detection systems, and antivirus software. These solutions can help to block malicious traffic and prevent malware infections.
- Keep systems and software up to date. Organizations should keep their systems and software up to date with the latest security patches. This will help to close vulnerabilities that could be exploited by attackers.
- Have a plan in place in case of an attack. Organizations should have a plan in place in case of a network attack. This plan should include steps for mitigating the attack and recovering from any damage.
