Keeping Your Network and Applications Safe from Cyber-Attack
Keeping your network safe from potential attacks by cybercriminals is a top priority for any business owner or manager who wants to avoid the disasters which might develop if a network were compromised by a clever cybercriminal. As the Internet, itself has grown, and businesses around the globe have increasing tied their fortunes to it, so too has criminal activity increased, because there are so many more opportunities to exploit businesses for monetary gain.
With every new safety measure developed by security experts, determined cybercriminals learn ways of circumventing those new safeguards, so that they can continue their money-making schemes by living off businesses developed by others. There is no such thing as an entirely safe business enterprise these days, simply because there are so many cybercriminals plying their trade, and because so many of them are extremely clever and skilled at what they do.
However, there are a number of precautions you can take which will at least limit your exposure to such attacks, and give you fighting chance of avoiding disaster by having your data, applications, or network infrastructure breached by a cyber-attack. Of course, there are some very expensive security measures you can have installed for extra protection on your network, but even those are not guarantees of safety. That being said, here are some very common precautions you can take, which will increase the likelihood that you can avoid the depredations of a cyber-attack.
Do Regular Backups to Stop Cybercriminals
One of the best things you can do to avoid having your data or applications held hostage, is to back up your data files and your applications every day. If a cyber-attacker should somehow gain access to your data and encrypt it so that it is unusable unless you pay for an encryption key, you would have no recourse but to pay the ransom amount, unless you had been backing up your data every day.
A recent survey conducted on the question of backups discovered that only 50% of small businesses routinely back their data up on a weekly basis, and that percentage shrinks to less than 23% for daily backups. When you have a backup of yesterday’s data, that insulates you against a hijacking of your data today, because all you have to do is restore yesterday’s backup and you have current data again, minus any transactions which may have occurred today. A cyber-attacker would be defeated.
Check Backup Processes Regularly
Having a regular backup routine is great, but in order for it to have any value, you have to be sure that it’s doing what you intended it to do, i.e. saving all your important data to a storage medium, from which it can be readily retrieved. Many small business managers have found that their backups weren’t really functioning properly when the time came that data needed to be restored.
When a data restore becomes critical is not the time to find out that you’ve had a problem for several weeks or several months, because crucial data may have been lost. You should also make a point of having a full understanding of exactly what is getting backed up. Obviously, the focus should be on business-critical data, but these days it’s sometimes also important to backup data which is resident on employees’ laptops because that can be just as important to business operations.
Keep Virus Protection Updated
Your first line of defense against cyber-attack is generally your firewall, so make sure your firewall is functioning properly and that it’s always enabled so that it can deflect any casual cyber-attacks. It’s also very important to make sure that your protection against viruses is as current as possible. Every time you get a security update from a software vendor, or from your operating system provider, those updates need to be applied promptly.
Since many of those security updates include protection against newly discovered viruses and security threats, they need to be applied to your system as soon as possible. Updating employee passwords regularly is also a good idea because passwords which go unchanged for long periods of time become vulnerable to interception by cyber attackers.
Check Your Transaction Logs Regularly
You should always make a practice of checking transaction logs daily for any unauthorized activity, either internal or external. It happens frequently enough that businesses which have suffered a cyber-attack could have prevented the fatal breach by regularly consulting transaction logs to discover previous break-in attempts. This should be done as a matter of routine just for normal business operations, but it can also be your first warning of an impending major cyber assault.
Indoctrinate Your Employees
It has rightly been said that in many cases, your employees are your weakest link in the security chain because they are the most exploitable. Employees who are not trained to use safe business practices and avoid security breaches are constantly being targeted by cybercriminals who are aware of the potential for exploitation.
Employees should be trained to be very cautious about opening email attachments, about providing passwords or other important company information in emails or via the social media, and they should be encouraged to change passwords monthly to protect against interception.
