Common Methods Used by Hackers to Gain Unauthorized Access to a Network

When it comes to network security, it is crucial to be aware of the common methods used by hackers to gain unauthorized access. By understanding these methods, organizations can better protect their networks and data from potential threats.

• Phishing: One common method used by hackers is phishing, where they disguise as a trusted entity to trick individuals into providing sensitive information such as login credentials.
• Brute Force Attacks: Hackers may also attempt to gain access by using automated tools to systematically try different username and password combinations until they find the correct one.
• Malware: Malicious software, such as viruses and trojans, can be used to infect systems and provide unauthorized access to hackers.
• Man-in-the-Middle Attacks: This method involves intercepting communication between two parties to eavesdrop or alter the data being transmitted.
• SQL Injection: By exploiting vulnerabilities in web applications that use SQL databases, hackers can manipulate the database to gain unauthorized access to the network.

It is essential for organizations to implement proper security measures such as strong passwords, multi-factor authentication, regular software updates, and employee training to prevent these common methods used by hackers.
