Study Notes
- Organizations globally recognize the importance of continuous investment in security for competitiveness.
- Failure to secure assets can lead to significant damage or bankruptcy.
- Enhancing the security posture involves aligning investments in protection, detection, and response.
Current Threat Landscape
- Threats are rapidly evolving due to constant connectivity and technological advancements.
- Any device is vulnerable to attack, especially with the proliferation of IoT.
- In 2016, DDoS attacks targeting DNS servers disrupted major web services.
- IoT-related attacks are increasing, with 32.7 million detected in 2018.
- VPNFilter malware was used in IoT attacks to infect routers and steal data.
- Many IoT devices have long-standing vulnerabilities, such as default passwords on security cameras.
- The rise in remote workers and BYOD policies increases vulnerability, especially with insecure implementations.
- Humans are the weakest link due to psychological manipulation through methods like phishing.
Phishing and its Consequences
- Phishing emails are still effective in compromising devices despite security controls.
- Wipro Ltd experienced a data breach due to a phishing campaign in April 2019.
- Phishing is often the entry point for attacks like ransomware, which cost millions in payments.
- During the first three months of 2016, the FBI reported that $209 million in ransomware payments were made.
Entry Points and Attack Vectors
- End-user entry points for attacks include connectivity between:
- On-premises and cloud
- BYOD devices and cloud
- Corporate-owned devices and on-premises
- Personal devices and cloud
- Cloud computing adoption is growing, with hybrid scenarios and IaaS being common.
- Organizations extending on-premises infrastructure to the cloud must assess and counter threats.
- Personal devices, if compromised, can risk company data through:
- Accessing corporate email
- Accessing SaaS applications
- Password reuse
- Security awareness training can help mitigate threats against the end user.
- Credentials are used to interact with applications and data, each having unique threat landscapes.
Authentication and Authorization
- Stolen credentials are a preferred attack vector, especially for financially motivated cybercrime.
- Companies must focus on authentication, authorization, and access rights of users.
- A user's identity is the new security perimeter, requiring specific security controls.
- Credential theft enables attackers to move laterally and escalate privileges.
- Defense in depth is a good strategy to protect a user's identity.
- Security policies for accounts should follow industry best practices.
- Multi-Factor Authentication (MFA) is increasingly used, including callback features.
- Continuous monitoring of identity is crucial to detect suspicious activities.
