Embedded Software Security Training
Embedded software security vulnerabilities are considerable. Like computers, many embedded systems have security vulnerabilities that can provide a way for a threat actor to gain access to the system.
Two types of security apply to embedded systems: physical security and software security, which should act in partnership to thwart cyberattacks on embedded systems.
For physical security, organizations can use a number of techniques to reduce vulnerabilities and provide protection against threats against embedded devices.
Embedded software security manages and responds to malicious behavior happening in the system, both during the initialization process and during run time. Software security features include authentication of a device to a network, firewalling network traffic and stringent hardening of system software to name a few.
As vulnerabilities are identified, software for embedded systems need to be mitigated with patches, which require software updates. Including security in the design phase helps ensure that an embedded system has a way to get updates and is capable of running new software.
Software-based attacks are one of the most common attacks on embedded software and target the brains of the system — the application that manages the devices. A successful attack on software allows a hacker to access data or gain control over an embedded system.
Searching for vulnerabilities in software design and code is the most popular vector of attack because it’s possible to conduct such an attack remotely. Also, a software-based attack doesn’t require specific knowledge from hackers, as they can use typical attacks like deploying malware and brute-forcing.
The most widespread software-based attacks involve:
- Brute-forcing access
- Overflowing the memory buffer
Design and software configuration go a long way to preventing embedded software security issues. Start with using safe languages. Also, research the embedded software development standards for the language of your choice before writing the first line of code.
Additionally, enable a secure boot. This feature allows a microprocessor to verify the cryptographic key and location of the firmware before executing it.
Disabling insecure and non-essential services also provides protection. To define such services, you need to analyze the operation of your system.
Along with better security safeguards in software development, the experts recommend knowing your system’s meantime to compromise (MTTC).
MTTC can be defined as the average time it takes an attacker to breach, or gain access, to the system and obtain the desired assets. Those assets could be data, or they could the system’s firmware or the ability to remotely control the device.
Cybersecurity professionals advise to make the MTTC large enough that potential attackers decide that the time and resources required to breach the system are not worth the payout, and therefore their time and effort.
