Explanation
Data loss prevention (DLP) is a set of tools and processes that aim to prevent unauthorized access, use, or transfer of sensitive data. DLP can help reduce the risk of further exfiltration using file storage sites on the internet by monitoring and controlling data flows across endpoints, networks, and cloud services. DLP can also detect and block attempts to copy, upload, or download sensitive data to or from file storage sites based on predefined policies and rules.

Using a SIEM tool to monitor network traffic in real-time and detect any anomalies or malicious activities Monitoring all network protocols and ports to detect suspicious volumes of traffic or connections to uncommon IP addresses Monitoring for outbound traffic patterns that indicate malware communication with command and control servers, such as beaconing or DNS tunneling Using a CASB tool to control access to cloud resources and prevent data leaks or downloads Encrypting data at rest and in transit and enforcing strong authentication and authorization policies

Explanation
Memory management is a technique that can allocate and deallocate memory for applications and processes.
Memory management can reduce vulnerabilities by avoiding code reuse, which is a technique that exploits a memory corruption vulnerability to execute malicious code that already exists in memory. Memory management can prevent code reuse by implementing features such as address space layout randomization (ASLR), data execution prevention (DEP), or stack canaries.

Explanation
Rainbow table is a type of attack that should concern a security administrator when reviewing the /etc/shadow file. The /etc/shadow file is a file that stores encrypted passwords of users in a Linux system. A rainbow table is a precomputed table of hashes and their corresponding plaintext values that can be used to crack hashed passwords. If an attacker obtains a copy of the /etc/shadow file, they can use a rainbow table to find the plaintext passwords of users.
