Hackers find more creative ways to gain access to a system

The world of cybersecurity is changing rapidly. Hackers are getting smarter and more sophisticated, and in an age of remote working, globalization, and endless third-party connections, attack methods and motivations are changing. Organizations need to be careful.

How are cyberattacks evolving?
Hackers no longer seek to hack a single system. As the SolarWinds hack showed, they often use an organization as a tunnel to more lucrative systems. SolarWinds was just a vehicle for bad actors to infiltrate government agencies. Additionally, ransomware rates are skyrocketing and hackers are deliberately preying on critical infrastructure, knowing that a company like Colonial Pipeline will pay quickly to avoid real-world devastation, as well as healthcare where EMR data pays off. a pretty penny.
It all comes down to access – what access points exist, who has access to them, and how well these individual and decentralized points are protected.
Moreover, the world is now decentralized. There is no longer a physical office, singular server room, or desktop computer protected by a single password. People are working from any place and anywhere while accessing different systems from their home or Wi-Fi cafe, and this trend is opening one breach after another that hackers can break through. They take full advantage of it.
How can your organization stay protected?
Perimeter defenses were once the norm in cybersecurity – castle and moat architecture. The main flaw was that a hacker was trying to break through a virtual wall, and once inside, they could access anything and everything. It was a single line of defense, and as we have seen time and time again, it could easily fall. If that defense is over and hackers find more creative ways to gain access to a system, what is the best method of protection?
Critical access management.
It all comes down to access – what access points exist, who has access to them, and how well these individual and decentralized points are protected. Critical Access Management contains a few key methods and practices that help organizations modernize their cybersecurity and stay secure in a changing world.
- Develop and implement strong access policies. There should be established rules in place to determine who should have access to what assets and what privileges they should have when accessing an asset. The secretary of a hospital’s human resources department does not need the same access rights to EMRs as an emergency physician. Role-based access policies, at least for internal employees, are an easy way to provision and de-provision access rights. Additionally, another access policy best practice is to use least privileged access, where a given user only has access to what they need to complete a task and nothing more. Building this architecture can help an organization gain visibility into these critical access points and better understand who can (and should) have access to these various points and assets.
- Use access controls. Access rules are only useful if they are enforced. Access controls are the techniques used to know when and how a user can exercise his access rights. Access controls can include anything from time-based access, to access notifications, to a department-wide or organization-wide access schedule. It is important to note that all access controls must follow the Zero Trust principle. Zero Trust, also known as Zero Trust Network Access, removes any implicit trust from internal or external users, instead applying the same granular controls across the board. This removes all gaps while tightening security even around the most common access points.
- Watch everything. You can’t know if your organization’s access policies and access controls are working properly without visibility. 51% of organizations do not monitor access to network resources and critical data, and this is a major problem. Whether it’s proactive and reactive observation or proactive and reactive analysis, looking at what’s happening with an endpoint is critical to understanding if the cybersecurity architecture in place is working. Additionally, monitoring can quickly alert an organization to anomalies and offer valuable insights in the event of a breach.
