Study Notes

Endpoint Security

Refers to protecting a business network when accessed by remote devices, such as smartphones.
Antivirus software protects individual computers, endpoint security protects the entire network.
Endpoint security uses a server/client model to protect various endpoints of an organization.
It's essential for securing larger and more complex organizations.
Firewalls filter network traffic based on security rules.
Endpoint security includes network filtering, patching, monitoring, and other security tasks to protect endpoints.

Antivirus Software

Focused on protecting single or multiple PCs.
A single piece of software responsible for scanning and protecting a home network.
A key component of endpoint security, along with firewalls.

Storage Security

Focuses on securing data storage systems and the data they contain.
Data breaches are often caused by failures in storage security.
Protects data from accidental damage, destruction, unauthorized access, or misuse.
Key security principles include confidentiality, integrity, and availability.

Storage Security Risks

Threats target vulnerabilities in storage systems and infrastructure.
Risks include unauthorized access, regulatory non-compliance, data corruption, data leakage, theft, and malware attacks.

Achieving Secure Data Storage

Data encryption
Access control mechanisms at each storage device or software
Protection against viruses, worms, and data corruption threats
Physical and manned security for storage devices and infrastructure
Layered/tiered storage security architecture

Data Security vs. Data Protection

Closely related to data protection.
Data security focuses on keeping private information from unauthorized access.
Data protection aims to ensure data availability after incidents like system failures or natural disasters.

Data Security Methods

Security: Firewalls, encryption, intrusion detection
Protection: Regular backups, data masking, disaster recovery

Storage Vulnerabilities

Lack of encryption
Cloud storage
Incomplete data destruction
Lack of physical security

Data Center and Cloud Storage

Data center storage refers to on-premises hardware for data and application storage.
Cloud storage, also known as utility storage, is off-premises computing.

Data Security Best Practices

Data storage security policies
Access control
Encryption
Data loss prevention
Strong network security
Strong endpoint security
Redundancy
Backup and recovery

System Architectures

Describe how a system interacts with other systems and the outside world.
Components include structure, functions, relationships, latency, bandwidth, and throughput.

Latency, Bandwidth, and Throughput

Latency is the time delay in data transmission.
Bandwidth is the maximum data transfer rate over a network.
Throughput is the actual amount of data successfully transmitted or processed.

Horizontal and Vertical Scaling

Horizontal scaling adds more servers to handle increased load.
Vertical scaling increases the capacity of existing servers.

Virtual Machines (VMs)

Software-based computer systems that emulate physical computer hardware.
Offer flexibility and efficiency in resource allocation.
