Data integrity verification involves using tools to compute the message digest of data. A message digest is a cryptographic hash function containing a string of digits created by a one-way hashing formula. This digest, which serves as a unique identifier, can be used to verify the integrity of copied data by comparing it to the original data's digest. If the digests match, it means the data has not been altered, ensuring its integrity.
References: The concept of data integrity and the use of message digests are fundamental security concepts taught in the Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) course. This course covers the essential skills and knowledge needed to monitor alerts and breaches, and to understand and follow established procedures for response to alerts converted to incidents

SIEM (Security Information and Event Management) systems are solutions that provide real-time analysis of security alerts generated by applications and network hardware. They collect, store, analyze, and report on log data for incident response, forensics, and regulatory compliance. On the other hand, SOAR (Security Orchestration Automation and Response) platforms allow organizations to collect data about security threats from multiple sources and respond to low-level security events without human assistance.

Load Balancing: HTTP(S) load balancing is one of the oldest forms of load balancing. This form of load balancing relies on layer 7, which means it operates in the application layer. This allows routing decisions based on attributes like HTTP header, uniform resource identifier, SSL session ID, and HTML form data.
Load balancing applies to layers 4-7 in the seven-layer Open System Interconnection (OSI) model. Its capabilities are: L4. Directing traffic based on network data and transport layer protocols, e.g., IP address and TCP port. L7. Adds content switching to load balancing, allowing routing decisions depending on characteristics such as HTTP header, uniform resource identifier, SSL session ID, and HTML form data.
GSLB. Global Server Load Balancing expands L4 and L7 capabilities to servers in different sites
