Pandemic brings major changes to external threat landscape

Stamford, Ct (USA)

The evolving threat landscape was ranked as the top driver impacting the information security organisation during the next three to five years, according to a recent survey by Gartner, Inc.  

“External risk is top of mind for security and risk management leaders in 2020, yet COVID-19 has proved how rapidly and how drastically such risks can change,” said Jonathan Care, senior research director at Gartner. “Bad actors are always looking to take advantage of worldwide events, such as the pandemic, to exploit new vulnerabilities and circumvent even the most advanced security controls.”

Remote working

As organisations worldwide moved to remote work spurred by COVID-19, the number of exposed remote desktop protocol (RDP) and virtual private network (VPN) services increased, and the widespread reliance on digital meeting solutions created new threat vectors. Security teams also had to develop new protocols for remote endpoint management and patching.

“Before the pandemic, most enterprises designed their risk appetites around the assumption that remote working was the exception, rather than the norm,” said Mr. Care. “When that scenario was flipped, risks such as always-on VPNs and bring-your-own-device, which were previously a lower priority for security leaders, suddenly became top of mind. This forced security teams to rapidly reassess their enterprise’s risk landscape and deploy new solutions and policies accordingly.”

Chaotic changes

Threat actors took advantage of the urgency and chaotic nature of the changes in working environments to leverage new tactics. Gartner has observed an increase in reports of coronavirus-related business email compromise (BEC) and phishing scams, including SMS phishing (“smishing”) and credential theft attacks.

COVID-19 also led to increased nation-state activity from advanced persistent threat (APT) groups targeting healthcare and essential services. These actors are using scan and exploit techniques, as well as password spraying that attempts to take advantage of unpatched vulnerabilities, to obtain bulk personal information, intellectual property, and national intelligence.

Invest in agile systems

In response to the dynamic nature of the immediate threat landscape, Gartner recommends that organisations invest in security solutions that are agile enough to evolve alongside it. “Many organisations waste time on legacy security technologies that have lost efficacy, or they continue to needlessly tune effective controls,” said Mr. Care. “Rather than trying to anticipate and block all possible threats, invest in solutions with detect and respond capabilities, which can assist with unknown threats and improve response efficacy when prevention fails.”

Gartner predicts that by the end of 2023, more than 50% of enterprises will have replaced older antivirus products with combined endpoint protection platforms (EPP) and endpoint detection and response (EDR) solutions that supplement prevention with detect and response capabilities. Extended detection and response (XDR) capabilities are also emerging to improve detection accuracy and security productivity.

Strategic evaluation

Security and risk leaders can use a continuous and adaptive risk and trust assessment (CARTA) strategic mindset to evaluate vendor products and determine how they can build up more adaptive defences by applying the concepts of prediction, prevention, detection and response.
