The Five Distinct Security Lifecycle Workflows
Embedded systems security lifecycle covers five distinct workflows and every one of them becomes very critical in maintaining the security and integrity of the system through its operational life.
1. Assessment
The first step in the determination process of what needs to be protected and the checking of levels of vulnerability and potential threats. It includes the process of risk analysis for determination of the likelihood and impact of security breaches.
- Threat modeling: Understanding how an attacker might compromise the system.
- Risk assessment: Prioritizing risks based on their potential impact and likelihood.
2. Implementation
Upon assessment, the security needs to be implemented. This could be from hardware to software or any other form of implementation.
- Secure coding practices: Developing software with security in mind to prevent vulnerabilities.
- Hardware security modules: Using physical devices that can manage, generate, and securely store cryptographic keys.
3. Monitor
It will monitor very well and respond to each threat in time. This includes the installation of intrusion detection systems, of which there should be security audits periodically.
- Intrusion Detection Systems (IDS): Software, tools, or devices used to monitor network traffic or system activities for purposes of detecting malicious activities or policy violations.
- Security audits: Regular reviews of security policies, procedures, and controls to ensure they are effective.
4. Response
The preordained plan helps in devising a way forward about the security breach in case it occurs, thus reducing damage. This contains the security breach and communication of the same to stakeholders.
- Incident response teams: Specialists trained to handle security breaches efficiently.
- Containment strategies: Techniques to limit the spread and impact of a breach.
Recovery is therefore concerned with getting the systems and the services back into normal operation, as well as reducing the risks that could have surfaced from the security breach after the immediate effects of the security breach have been contained and mitigated.
5. System restoration
Procedures to restore IT systems and operations to their state before the breach.
What is Embedded System Security?
Embedded Systems have become the world’s critical components in different industries such as automotive, telecommunication, medical devices manufacturing, etc. These systems most often have a great impact on critical infrastructure or sensitive data processing. So their security is always a critical issue and sometimes may be extremely important.
The security of an embedded system encompasses different types of technologies such as encryption and authentication to guard these systems from intrusion, attacks, and unauthorized access. Here, this article states the main points of embedded system security, digging deep into its importance, the way it is done, and the difference between traditional cybersecurity approaches.
