SC-7 Boundary Protection
Mitigates 156 ATT&CK techniques, used by 12 threats in this month's news.
Why it matters this month
Threats in SecurityTabs news using techniques this control mitigates.
Weaknesses it helps against
Through the techniques typically used to exploit them (CTID, CISA KEV).
- CWE-1199 techniquesImproper Restriction of Operations within the Bounds of a Memory BufferCode reads or writes past the end of a buffer, the root of most classic memory-corruption exploits.
- CWE-1209 techniquesBuffer Copy without Checking Size of Input ('Classic Buffer Overflow')Input is copied into a fixed-size buffer without checking its length, overwriting whatever follows.
- CWE-1219 techniquesStack-based Buffer OverflowAn overflow on the stack can overwrite the return address and redirect the program to attacker code.
- CWE-1229 techniquesHeap-based Buffer OverflowAn overflow on the heap corrupts neighbouring objects, often turned into code execution.
- CWE-1257 techniquesOut-of-bounds ReadCode reads beyond a buffer, leaking secrets such as keys or memory addresses that defeat other defences.
- CWE-207 techniquesImproper Input ValidationInput isn't checked against what the program expects; the umbrella cause behind many specific flaws.
- CWE-4167 techniquesUse After FreeThe program keeps using memory after releasing it, so an attacker who controls what lands there next can hijack execution.
- CWE-7877 techniquesOut-of-bounds WriteData is written outside the memory it belongs to; the most common root cause of exploited memory bugs.
- CWE-2846 techniquesImproper Access ControlRestrictions on who can access a resource are missing or wrong.
- CWE-2856 techniquesImproper AuthorizationThe system checks who you are but not whether you're allowed to do what you're asking.
