what are the two types of security attacks?

The dangerous data is subsequently read Whatever the motive, many security teams are struggling to keep their IT systems secure. A distributed denial-of-service (DDoS) attack is similar in that it also seeks to drain the resources of a system. Security control considerably helps an organization analyze security gaps and external attacks and set the current security position. Active network attacks involve modifying, encrypting, or damaging data. DNS Tunneling is a type of cyberattack that leverages domain name system (DNS) queries and responses to bypass traditional security measures and transmit data and code within the network. While there are legitimate and legal uses for keyloggers, many uses are malicious. Types of active attacks are as follows: Masquerade Modification of messages Repudiation Replay Denial of Service Masquerade - Masquerade is a type of cybersecurity attack in which an attacker pretends to be someone else in order to gain access to systems or data.
