How Can SMEs Safeguard Their Businesses from Cyber Attacks?

Written by Harshit Agarwal | Mar 26, 2019 4:08:02 PM

While many things contribute to a business’s success, a minor data breach can bring it down.

A data breach is one of the major concerns for organizations in today’s world. While big companies manage to bounce back from it, 60% of small companies run out of business within 6 months of a cyber attack or data breach.

Data leaks lead to a lack of customer trust, and businesses can take a hit. This is why cybersecurity is crucial for any company, big or small, especially when it comes to cybersecurity for SMEs.

Taking measures to monitor suspicious activity is vital these days as it can make or break the financial security and future of a business.

When it comes to cybersecurity for SMEs and enterprises, especially network security, there are several abnormalities that constitute “suspicious activity.” A business needs to be able to recognize these behaviors to help find the origin or nature of the data hack. This will help a business respond quickly and implement corrective measures to minimize the threat and curb damage. Suspicious activity could include abnormal database activity or access patterns, file changes, or anything out of the ordinary that could indicate a cyber attack.

Some of the activities that companies should keep an eye out for

 

Database Activity

Unusual activity in your database could result from internal or external attacks. Either way, it’s imperative to watch out for crucial signs like a remarkable growth in data, any changes made to permissions, or user changes.

Abuse of Accounts

When privileged accounts are abused, it indicates an internal attack. You need to look out for odd sharing access, access to sensitive information when it’s not needed, or modified audits.

Unusual User Access

When there are suspicious changes to user access, this indicates an external hacker trying to gain access to your business network. You need to track accounts being accessed at odd hours, remote access attempts, multiple failed login attempts, or a discrepancy between the device and a user ID.

Changes to Files

Another sign of a data attack is when file configuration changes are made. This includes additions, deletions, and modifications. It might be that a hacker has accessed the network and is trying to cover the trail so that they are not discovered.

Network Behaviour

When it comes to your network, you need to watch out for unauthorized scans, abnormal changes in the network’s performance, any protocol violations, or traffic with odd targets or origins. These are critical signs of an external hack.

Unauthorized Port Access

Sometimes, unauthorized port access boils down to an internal accident. However, suspicious access could also mean data has already been stolen or there has been a malware attack.

Changes detected by end users

Sometimes, end users may notice suspicious activities before the company does. This usually happens with smaller businesses that have fewer security measures implemented. End users may experience weird antivirus notifications, excessive pop-ups, unauthorized toolbars, or notice that the network or device slows down.

Suspicious activity doesn’t necessarily mean the same thing for every organization. Between large and small businesses, things and the reasons for hacking will differ. Nonetheless, having security measures in place to check these activities could prevent an SME from folding.

Businesses can learn from past data breaches and be better prepared for future attempts. Some important measures that you can implement to ensure your data security is top-notch are:

• Installing firewalls
• Malware protection
Strong password policies
Regular review of performance, error reports, network alerts, and traffic
File integrity monitoring
Instructing end users to report suspicious activity
Incident and failure response strategies
Regular risk assessments

More importantly, employees are known to be the weak link when it comes to cybersecurity. It’s essential to educate and inform employees of the different types of suspicious activity and how to avoid malware attacks and viruses.

Cybersecurity and data protection are critical for any business venture, whether it's an SME or a large corporation, as it can determine its success or failure it. Cyber attacks don’t just cost a business financially but also tarnish the brand’s image and reputation. Even with more advanced technology and security protocols in place, hackers are constantly finding new ways to break through it. A business always needs to stay two steps ahead regarding cybersecurity.
