Computer security is vital for all businesses and has never been more important. Our computers are used for processing important and private documentation, accounting, account details and so much more. This all needs to be kept under lock and key, if it was to get into the wrong hands it could be devastating for you and your business.
What is Network Security?
IT security is a set of strategies, tools, behaviours and rules designed to prevent this type of situation and to guarantee the integrity, availability and confidentiality of data.
Why is Network Security so Important?
Viruses, malware, and spam are unfortunate terms that we’re all aware of and have likely experienced. They are often heard of in the news and flooding our inboxes, something we all struggle to avoid.
Crypto locker is a famous virus, which penetrates computers and encrypts all the files present inside it, asking for a ransom in cash to decode them and have them available again. It’s more common than you may believe. According to a recent survey by the American security institute, 120,000 attacks per day are recorded worldwide, with annual increases of around 50%. These attacks cause so much damage, estimated at over £2bn. Protecting your computers and networks against viruses like this is more crucial than ever before. Fortunately, there are practical measures to tackle some of these problems.
Practical Measures to Increase IT Security
IT security begins with those who live in the company: adopting responsible behaviour is the first step in trying to protect their data. Here are some simple practices to be implemented immediately to reduce the risk of viruses and hackers.
Update Operating Systems
Operating systems, or those programs that allow computers to work, are unfortunately the cause of so many security problems. Microsoft and Apple (the leading vendors of operating systems) often detect security flaws – so-called “bugs” – that could allow a hacker to take control of the network. They periodically issue update packages to remedy these flaws. It’s therefore very important to update the operating system and eventually replace them when they are no longer supported.
Install Professional Antivirus
When it comes to installing an antivirus, many opt for the free ones, a choice that often turns out to be disastrous. Many free antiviruses do not guarantee complete computer security, because they lack important features such as firewalls, content filtering and antispam that are able to detect and manage threats of any kind. Professional antivirus products have all these features, at a reasonable cost. It is more convenient to face a small investment in terms of prevention and IT security than to risk extremely high costs to restore a damaged system.
Use Secure Passwords
As for the passwords, for convenience or laziness, we often tend to use really simple ones, leaving computers, servers and network equipment lacking. This is a big mistake: there is software used by hackers, which allows them to scan the internet looking for computers with ineffective or null passwords. At that point, taking control of it turns out to be child’s play and the machine becomes a so-called “zombie system” to unleash any kind of attack. Choosing strong passwords is a great way to keep out malicious hackers who, rather than wasting time trying to force them, continue to search for other PCs to compromise.
Relying on Professionals
Finally, it is important to entrust network security to industry experts who do this by trade and know all the procedures and tools to ensure maximum IT security. If you would like any help or advice regarding network security for your business, please feel free to get in touch.
