There are numerous types of cyber attacks that can be perpetrated against an individual or a business. One of the most common forms of cyber attack is ransomware, which is a type of malicious software that encrypts the victim’s data and holds it for ransom. Phishing attacks are also widespread, entailing the use of deceptive emails, texts, or phone calls to trick individuals into divulging sensitive information such as usernames and passwords. Another type of cyber attack is a distributed denial-of-service (DDoS) attack, which overwhelms a target’s server with an excessive amount of traffic, making it inaccessible to legitimate users. Additionally, there are malware attacks that involve installing harmful software on a victim’s computer, and social engineering attacks that exploit human psychology and trust. Each of these cyber attacks poses a different risk and requires specific security measures to prevent and mitigate.

Purpose of cyber attacks (e.g. financial gain, espionage, activism, etc.)

Cyber attacks exploit different vulnerabilities in a system, and they can be caused by various factors. Identifying these vulnerabilities can help organizations prevent potential security breaches. One of the most common vulnerabilities is weak or reused passwords. Users tend to use the same passwords for multiple accounts, making them easy targets for cybercriminals. Another vulnerability is unsecured networks, which are often found in public Wi-Fi hotspots or unsecured enterprise networks. Such networks provide hackers with an entry point to launch attacks. Outdated software and applications also pose a severe vulnerability as they often lack the latest security patches and updates, making them susceptible to known vulnerabilities. Moreover, phishing attacks remain a popular method for cybercriminals as they use social engineering tactics to trick users into revealing confidential information, such as login credentials. By understanding these common vulnerabilities, individuals and businesses can take proactive measures to protect their digital assets.

Methods of preventing or mitigating cyber attacks (e.g. antivirus software, employee training, etc.)
