Endpoint Security: 3 Big Obstacles to Overcome

In a report released earlier this year on the topic of next-generation endpoint security, Enterprise Security Group (ESG) analyst Jon Oltsik observed that enterprises and antivirus vendors alike find keeping up with endpoint security difficult because of the sophisticated nature, prolific volume and exponentiating complexity of attacks.

"CISOs could anticipate that 40% to 50% of new sophisticated malware attacks could evade endpoint AV, compromise PCs, and act as a beachhead for advanced cyber-attacks," wrote Oltsik. "CISOs realize today that, regardless of the controls they deploy, some malware will sneak through, so they need continuous monitoring and visibility of endpoint behavior."

"Continuous," however, has practical limits.

ESG found that the top endpoint-security challenge—as indicated by 25% of the 385 cybersecurity professionals surveyed for ESG's report—was respondents' InfoSec teams taking too long dealing with too many security alerts, many of which are "false alarms." This suggests a—ahem—continuous trend.

In a separate ESG study last year on the topic of security operations challenges, 36% of the 150 IT and cybersecurity professionals surveyed reported that "keeping up with the volume of security alerts" was their top incident response challenge. Little wonder that enterprise security alerts are commonly treated as so much noise. Of those surveyed, 31% admitted that their organizations ignore at least 50% of their security alerts; an additional 34% reported that their organizations ignore 26% to 50% of their security alerts.

Endpoint-Security Obstacle No. 1: Insufficient Automation

ESG and other pundits have concluded that proper endpoint-security management demands enhanced automation and machine-learning tools—with the clearing out of security alerts being but one use case. 

In an Industrial Internet Consortium (IIC) whitepaper on best practices in endpoint security, published in March, IIC emphasized automated protocols as a common denominator for both secure endpoint identities and secure attestations. Automation driven by public-key cryptography standards (PKCS), reported IIC, is critical to ensuring safety and certainty in the digital supply chain of certificates, firmware updates, etc.—helping to keep at bay any malware that might otherwise slip through (sub)standard AV solutions.

Indeed, 17% of the ESG next-generation endpoint security study respondents identified their AV software as their top endpoint-security challenge, while 19% pointed to too many manual processes because of their lack of integrated endpoint-security automation. (It should be noted that respondents were allowed to select up to two responses.)

When it comes to malicious bots and the like, some contend that fighting AI with AI can be a losing battle. Consequently, a wholesale ban on non-whitelisted bots can help cut down on endpoint-security alerts and keep them manageable.

Nonetheless, IIC maintains that automated endpoint updates should be reliable without in-house whitelists or blacklists (typically manually input) as a matter of scalability.

"The number of attacks on industrial endpoints has grown rapidly in the last few years and has severe effects," Steve Hanna, co-author of the IIC whitepaper, said when the best practices document was released. "Unreliable equipment can cause safety problems, customer dissatisfaction, liability, and reduced profits."

Endpoint-Security Obstacle No. 2: Legacy Devices

Despite these admonitions against equipment unreliability, the authors of the whitepaper make allowances for legacy endpoints. Still, they concede (1) that some of the most effective endpoint-security measures are embedded in hardware (typically not an option for legacy devices), and (2) that inadequately secure legacy endpoints must rely on network-security measures.

This latter point defeats the purpose of endpoint security. Why struggle against the most modern, most secure endpoints when there are more vulnerable legacy endpoints to be pwned?

To be fair, it is feasible to implement lower levels of trust across legacy endpoints—but perhaps impractical. Legacy endpoints are maintained for a reason (usually involving cost). Presumably, therefore, these legacy endpoints still need levels of accessibility appropriate for more up-to-date endpoints—despite the confidentiality and integrity risks.

Endpoint-Security Obstacle No. 3: Poor Security Culture

This preference among enterprises—even among InfoSec workers—to mortgage endpoint security for agility's sake is further evident in ESG's latest findings:

ESG is not alone in making such findings. Verizon Wireless, for instance, reported in February that nearly one-third of 600 surveyed mobility professionals admitted that their organizations sacrificed mobile security in favor of business agility—at significant risk.

More depressingly, in a world where enterprises can be split into the hacked and the unaware of being hacked, a doubtlessly overly optimistic 10% of the ESG survey respondents reported having no endpoint-security challenges whatsoever.
