Study Notes
Firmware Vulnerabilities
- Firmware is software embedded in a hardware device, such as a router or printer.
- Firmware controls the basic functions of the device and can be updated by manufacturers or users.
- Outdated, corrupted or tampered with firmware can expose the device to security risks.
- An attacker could exploit firmware vulnerabilities to gain unauthorized access, modify device settings or install malware.
Firewall Configuration
- "Deny any" policies should be added to the bottom of the Access Control List (ACL).
- A "deny any" policy can cause company servers to be unreachable if not implemented correctly.
- It is important to test the "deny any" policy in a non-production environment before enabling it in the production network.
Backup Data Center
- Warm Sites are a good choice for a backup data center when cost-benefit is the primary requirement and the Recovery Time Objective (RTO) and Recovery Point Objective (RPO) are around two days.
- Warm Sites are not fully equipped, but have the fundamentals in place.
- Warm Sites can be operational within a few days, making them cheaper than Hot Sites, but with a slight delay.
Secure Hard Drive Wiping
- Organizations should sanitize hard drives before sending decommissioned systems to recycling to securely remove sensitive data.
- Sanitization ensures that data is removed from storage devices before they are repurposed or disposed of.
Input Validation
- Input validation is a security technique where data input is checked according to defined specifications.
- This technique prevents the injection of malicious code into a system or application.
Reducing Phishing Impact
- Update Endpoint Detection and Response (EDR) policies to block automatic program execution after a phishing link is clicked.
- EDR systems monitor and analyze the activity of endpoints, detecting threats and enabling better protection.
Automated Provisioning
- A user provisioning script can help automate the creation of new user accounts.
- This simplifies the account creation process and reduces manual error, ensuring consistency and compliance.
Security Control Types
- A Security Information and Event Management (SIEM) system is a detective security control.
- A SIEM collects, correlates and analyzes logs from various sources, providing a centralized view of security status and incidents.
- A detective control alerts or reports on violations or incidents after they occur.
Application Hosting for Low Cost
- Serverless frameworks are a low-cost, cloud-based solution for hosting applications.
- Serverless frameworks allow developers to focus on code without managing servers.
Data Hiding
- Steganography is a technique where information is hidden within another medium, such as an image.
- This hidden information is not visible to the general observer, and can only be extracted with a specific key.
Legal Holds
- A legal hold is a process where an organization retains potentially relevant information for a legal case.
- When a company is compromised, attorneys may request a legal hold, requiring retention of all communication related to the security breach until further notice.
- This prevents the destruction of evidence and ensures potential evidence is preserved for legal proceedings.
Content Filter Categorization
- Updating the categorization of a website in a content filter can resolve issues with access being blocked unnecessarily.
- Adjust the categorization of a website to reflect its actual function.
Insider Threats
- Insider threats occur when someone with legitimate access to a network or data abuses their privileges to cause harm.
- An insider threat can be motivated by factors such as financial gain, revenge, or espionage.
- Actions taken by a domain user encrypting files on a databse server indicate an insider threat.
Disabling Access After Departure
- Automating the process of disabling access for former employees upon departure is critical for enhancing security posture.
- This ensures that terminated employees no longer have access to company resources.
- Disabling access can be automated through scripts, tools or workflows triggered by defined events like termination or resignation.
High Availability Networking
- Ease of recovery is an essential consideration when designing a high availability network.
- High availability networks aim to minimize downtime and ensure continuous service.
- Ensuring a seamless and rapid recovery process is vital for ensuring network uptime and minimal disruption.
