September is time for back to school and back to business! This is a great time to get serious about training your employees to understand their role in helping a business or organization stay safe.

Perfect timing!  Here's a phishing email that just arrived, and a prime example to show a few tips on how to spot a problem email.  The subject of the email was "subscription renewal", and at the beginning of the month a lot of these may arrive in anyone's inbox.  This one immediately caught my eye because the preview text showed "Hello dear".  The other thing to note is that we've all been taught to not "click on the link", but this one invites us to call a number.  That's a common new tactic and in the never ending cat and mouse game as computer users become more aware of dangerous links, the cyber criminals just come up with a new twist.

When the pandemic hit, businesses all over the globe had to shift to remote work almost overnight.  Now, with the vaccine rollout in full swing, the hybrid work model is gaining popularity. This allows employees to work from home, the office or split their time between both. According to a recent Accenture Report, close to 65% of businesses have adopted a hybrid model, and most workers prefer it that way.  

However, a distributed workforce comes with its own set of challenges. One of the primary concerns of IT leaders across the globe is the unprecedented increase in cybercrime. The FBI reports that cybercrime has shot up by almost 300% since the start of the pandemic.

Relying on one basic security solution will, therefore, prove to be futile against sophisticated attack vectors.  You may have seen advertisements on-line or on television promoting a single security solution that solves all your cybersecurity problems, but it just doesn't work like that! This is where an approach like Defense in Depth (DiD) finds its relevance.  If you've attended any of our security workshops, we also often refer to this as "layers of security".

Defense in Depth is a cybersecurity approach in which multiple defensive methods are layered to protect a business. Since no individual security measure is guaranteed to endure every attack, combining several layers of security is more effective.  

This layering approach was first conceived by the National Security Agency (NSA) and is inspired by a military tactic of the same name. In the military, layers of defense help buy time. But in IT, this approach is intended to prevent an incident altogether.

While Defense in Depth is critical to protecting your business against evolving cyberthreats, it’s an undertaking that requires time, extensive knowledge and experience. Partnering with a technology service provider like Ekaru can simplify the process, reduce stress and minimize opportunities for error.

How Your Small Business Can Help Defend Against Threats

All of the major cybersecurity protocols and frameworks (NIST, HIPAA, CMMC, etc) focus on three primary areas of control:

1. Administrative Controls
The policies and procedures of a business fall under administrative controls. These controls ensure that appropriate guidance is available and that security policies are followed.

Examples include hiring practices or employee onboarding and offboarding protocols, data processing and management procedures, information security policies, vendor risk management and third-party risk management frameworks, information risk management strategies, etc.

2. Technical Controls
Hardware or software intended to protect systems and resources fall under technical controls. Examples of technical controls are firewalls, configuration management, disk/data encryption, identity authentication (IAM), vulnerability scanners, patch management, virtual private networks (VPNs), intrusion detection systems (IDS), security awareness training, etc.

3. Physical Controls
Anything aimed at physically limiting or preventing access to IT systems falls under physical controls.  Examples include  fences, keycards/badges, CCTV systems, locker rooms, etc.


Essential Elements of Defense in Depth:

A technology service provider will help you implement all the elements of an effective Defense in Depth strategy to minimize the chances of threats seeping in through the cracks. These elements include:

1. Firewalls
A firewall is a security system comprised of hardware or software that can protect your network by filtering out unnecessary traffic and blocking unauthorized access to your data.  We strongly advise implementing a "business class" firewall and not simply relying on what your Internet provider installed.

2. Intrusion Prevention and Detection Systems
Intrusion prevention and detection systems scan the network to look for anything out of place. If a threatening activity is detected, it will alert the stakeholders and block attacks.

3. Endpoint Detection and Response (EDR)
Endpoint Detection and Response (EDR) solutions operate by constantly monitoring endpoints to find suspicious or malicious behavior in real time.

4. Network Segmentation
Once you divide your business’ network into smaller units, you can monitor data traffic between segments and safeguard segments from one another.  If there's a breach in one segment of the network, the other segments may be protected.

5. The Principle of Least Privilege (PoLP)
The principle of least privilege (PoLP) is a cybersecurity concept in which a user is only granted the minimum levels of access/permissions essential to perform their task.  If an employee doesn't need access to protected information, they should not have access.  In many cases, over time data winds up being stored in a way that multiple people have access to it when they don't need to.  Conduct regular audits of the data you hold.

6. Strong Passwords
Poor password hygiene, including the use of default passwords like “123456” or “admin,” can put your business at risk. Equally risky is the habit of using the same passwords for multiple accounts. To protect your accounts from being hacked, it’s essential to have strong passwords and an added layer of protection by using practices such as multifactor authentication (MFA). 

At the start of the pandemic, there was an intense scramble to enable remote work for many in the “laptop class”.  For many people, working from home was a welcome change from stressful commutes and a hectic family life. Some people are scrambling to get back to the office to escape makeshift dining room desks that compete with family life and chaos, or just crave the social interaction, creative interactions, and other structure that office environments provide. You might be in a hybrid situation, where you are putting in hours both at home and in the office. Either way, you’re back and you’re ready to go.

Here's a re-cap of our recent community cybersecurity training event.  Cybersecurity these days is like a game of chess.  For every move, there's a counter move.  As people put more technology protection in place, the cyber criminals just get more clever.  User awareness is often the key to staying safe!  Will your employee click on that dangerous link?  It takes just one wrong click to do a lot of damage.  The more you and your team know about the latest threats, the better.  We were pleased to host close to 100 local small business leaders from Westford, Acton, Littleton, Chelmsford, Concord, Waltham, Southborough, Northborough, and Wellesley during our recent small business cybersecurity awareness training session. Education is a key part of Ekaru's mission, and here are a few highlights from the event.

Technology is an important part of any cybersecurity plan, but technology can only take you so far.  Getting the right firewall, security patches, antivirus, and other protections are an important part of your small business security foundation, but the last line of defense is your employees.  Will they click on that link?
