common cyber security threats

 

Malware

Malware, or malicious software, is a common type of cyberattack that encompasses various subsets such as ransomware, trojans, spyware, viruses, worms, keyloggers, bots, and cryptojacking. These programs or code are created with the intent to harm computers, networks, or servers.

Phishing

Phishing attacks involve tricking individuals into revealing sensitive information, such as passwords or credit card numbers, by disguising as a trustworthy entity through fraudulent emails or websites.

Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) attacks

DoS attacks overwhelm a system with traffic, rendering it unable to respond to legitimate requests. In DDoS attacks, multiple compromised devices are used to launch the attack.

Social engineering

Social engineering involves manipulating individuals into divulging confidential information or performing certain actions through psychological manipulation

Password attacks

Attackers may use various techniques, such as brute-force attacks or dictionary attacks, to gain unauthorized access to systems or accounts by guessing or cracking passwords.

Insider threats

Insider threats involve individuals within an organization who misuse their privileges or access to deliberately harm the organization’s security.

It is important to implement comprehensive security measures, such as regularly updating software, using strong and unique passwords, practicing safe browsing habits, and educating employees about cyber threats, to mitigate these common cyber security threats.
