1.6 NETWORK SECURITY

1.6 NETWORK SECURITY

1. A Penetration test is when a hacker tries to hack a system on purpose to test the security is called a PENETRATION TEST. This is a prevention action to a security.

2. A Network Forensic is when a companion is hacked and the forensic is to get good hackers to gather information about the details and why it happened.

3. A Poor Network Policy is when every company has network IT policies to help protect the companies data and service but needs availability to ensure easy access to IT assets and networks by authorized users.

4. A Brute Force Attack is the simplest method to gain access to a site or server (or anything that is password protected). It tries various combinations of usernames and passwords again and again until it gets in. This repetitive action is like an army attacking a fort.

5. Password Features - At least 8 characters—the more characters, the better. A mixture of both uppercase and lowercase letters. A mixture of letters and numbers. Inclusion of at least one special character, e.g., ! @ # ? ] Note: do not use < or > in your password, as both can cause problems in Web browsers.

6. Ciphertext is also known as encrypted or encoded information because it contains a form of the original plaintext that is unreadable by a human or computer without the proper cipher to decrypt it. Decryption, the inverse of encryption, is the process of turning ciphertext into readable plaintext.

7. SQL injection example. An attacker wishing to execute SQL injection manipulates a standard SQL query to exploit non-validated input vulnerabilities in a database. This combines two unrelated SELECT queries to retrieve data from different database tables.

8. A destructive program that masquerades as a benign application. Unlike viruses, Trojan horses do not replicate themselves but they can be just as destructive. One of the most insidious types of Trojan horse is a program that claims to rid your computer of viruses but instead introduces viruses onto your computer.
