| .002 | Дефейс внешних систем |
An adversary may deface systems external to an organization in an attempt to deliver messaging, intimidate, or otherwise mislead an organization or users. External Defacement may ultimately cause users to distrust the systems and to question/discredit the system’s integrity. Externally-facing websites are a common victim of defacement; often targeted by adversary and hacktivist groups in order to push a political message or spread propaganda.(Citation: FireEye Cyber Threats to Media Industries)(Citation: Kevin Mandia Statement to US Senate Committee on Intelligence)(Citation: Anonymous Hackers Deface Russian Govt Site) External Defacement may be used as a catalyst to trigger events, or as a response to actions taken by an organization or government. Similarly, website defacement may also be used as setup, or a precursor, for future attacks such as Drive-by Compromise.(Citation: Trend Micro Deep Dive Into Defacement)

| Data Backup |
Data Backup involves taking and securely storing backups of data from end-user systems and critical servers. It ensures that data remains available in the event of system compromise, ransomware attacks, or other disruptions. Backup processes should include hardening backup systems, implementing secure storage solutions, and keeping backups isolated from the corporate network to prevent compromise during active incidents. This mitigation can be implemented through the following measures: Regular Backup Scheduling: - Use Case: Ensure timely and consistent backups of critical data. - Implementation: Schedule daily incremental backups and weekly full backups for all critical servers and systems. Immutable Backups: - Use Case: Protect backups from modification or deletion, even by attackers. - Implementation: Use write-once-read-many (WORM) storage for backups, preventing ransomware from encrypting or deleting backup files. Backup Encryption: - Use Case: Protect data integrity and confidentiality during transit and storage. - Implementation: Encrypt backups using strong encryption protocols (e.g., AES-256) before storing them in local, cloud, or remote locations. Offsite Backup Storage: - Use Case: Ensure data availability during physical disasters or onsite breaches. - Implementation: Use cloud-based solutions like AWS S3, Azure Backup, or physical offsite storage to maintain a copy of critical data. Backup Testing: - Use Case: Validate backup integrity and ensure recoverability. - Implementation: Regularly test data restoration processes to ensure that backups are not corrupted and can be recovered quickly. |

Implementing best practices for websites such as defending against Exploit Public-Facing Application (Citation: OWASP Top 10 2017). Consider implementing IT disaster recovery plans that contain procedures for taking regular data backups that can be used to restore organizational data. (Ready.gov IT DRP) Ensure backups are stored off system and is protected from common methods adversaries may use to gain access and destroy the backups to prevent recovery. |
Обнаружение
Monitor external websites for unplanned content changes. Monitor application logs for abnormal behavior that may indicate attempted or successful exploitation. Use deep packet inspection to look for artifacts of common exploit traffic, such as SQL injection. Web Application Firewalls may detect improper inputs attempting exploitation.
