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.
