Why traditional security defenses fail

Specifically reflected in the following aspects: lack of analysis of the content of data channels such as emails and file downloads. Zero-day attacks and APT attacks often embed malicious programs in these data channels and bypass various defense products to enter the corporate intranet.

Lack of parsing of document formats Zero-day attacks and APT attacks bypass the detection of traditional defense products by embedding attack codes into document content (such as PDF, WORD, pictures, etc.).

Lack of detection of encrypted/encoded malware Malware that is encrypted or encoded can mask or alter its characteristics, thereby bypassing traditional defense methods of detection based on signatures and known characteristics.

Unable to detect 0days. Attacks that exploit 0days (vulnerability information that is known to system vendors before they are aware of and release relevant patches) can easily bypass traditional security defense products.

Unable to detect internally initiated data connections. After an attacker successfully invades an enterprise, he or she steals important information assets through encrypted connections. Traditional defense products cannot detect this.
