Practical ways to keep your IT systems safe and secure

The majority of small firms use electronic devices for business and retain personal data. Maintaining the confidentiality of the information is essential for the good name and daily operations of your company. Remain vigilant as inadequate security measures can render you and others susceptible, and cyber-attacks impact companies of all kinds.

These are some doable actions that you, along with your employees, can do to strengthen data security.

Back up your data

Regular data backups are advised. If you use an external storage device, store it somewhere else than your primary place of business. If at all feasible, lock it away and encrypt it. In this manner, you reduce the possibility of losing all of your data in the event of a fire, flood, or break-in.

Examine your backup. When you most need it, you don’t want to learn that it didn’t work. To ensure that any malicious activity doesn’t reach your backup, make sure it isn’t connected to your live data source.

Be aware of your surroundings

For example, if you’re on a train or in a shared workspace, other people may be able to see your screen. A privacy screen might help you.

Be wary of suspicious emails

It’s important for you and your team to recognize questionable emails. Watch out for warning indications including poor grammar, requests for payment, and demands that you act immediately. The sophistication of email attacks is increasing due to new technologies. Phishing emails may seem to be from reputable sources. Consult the sender if you’re unsure. The NCSC offers helpful training resources to assist you and your employees in identifying questionable emails.

Protect your device when it’s unattended and Use strong passwords and multi-factor authentication

On laptops, tablets, cellphones, email accounts, and any other device or account that stores personal data, make sure you use strong passwords. They have to be hard to figure out. It is suggested by the National Cyber Security Centre (NCSC) to use three random word

Lock your screen when you’re temporarily away from your desk to prevent someone else accessing your computer. If you do need to leave your device for longer, put it in a secure place, out of sight.

Make sure your Wi-Fi connection is secure

Using an unsecured connection or public Wi-Fi could expose personal information. When connecting to the internet, you should always use a secure connection. Use a secure Virtual Private Network (VPN) if you’re on a public network.

Take care when sharing your screen

Sharing your screen in a virtual meeting may show your device to others exactly as you see it, including any open tabs or documents. Before sharing your screen, you should close anything you don’t need and make sure your notifications and pop-up alerts are switched off.

Don’t keep data for longer than you need it

Getting rid of data you no longer need will free up storage space. This also means you have less personal information at risk if you suffer a cyber-attack or personal data breach.

Dispose of old IT equipment and records securely

You must make sure no personal data is left on computers, laptops, smartphones or any other devices, before you dispose of them. You could consider using deletion software, or hire a specialist to wipe the data.

Factories of the 21st century

Data centers have been described as the factories of the 21st century. These facilities contain servers that store and process digital information. When we hear about data being stored “in the cloud,” those data are really being stored in a data center.

 

But contrary to the ephemeral-sounding term “cloud,” data centers are actually incredibly energy- and capital-intensive infrastructure. Servers use tremendous amounts of electricity and generate large amounts of heat, which in turn requires extensive investments in cooling systems in order to keep servers operating. These facilities also need to be connected to fiber optic cables, which deliver information via beams of light. In most places, these cables – the “highway” part of the “information superhighway” – are buried along the rights of way provided by existing road and railroad networks. In other words, the pathways of the internet are shaped by previous rounds of development.

An economy based on information, just like one based on manufacturing, still requires a human-made environment. For the data industry, taking advantage of the places that have the power capacity, the building stock, the fiber optic connectivity and the proximity to both customers and other data centers is often central to their real estate strategy.

How Long Do You Expect Your Hardware to Last?

Business owners invest in various computer hardware and networking systems and then forget about them until something goes wrong. Parts breaking down, disasters, and company changes are common reasons why businesses replace their hardware. To avoid major downtime and financial headaches, it’s important to know how long computer hardware and networking systems last.

Networking Infrastructure

There are different types of networking systems. The most common are Local Area Network (LAN) and Wireless Local Area Network (WLAN). A typical LAN infrastructure can last anywhere between 10 and 15 years while a regular WLAN lasts an average of two years. You know it’s time to replace your networking infrastructure when you start experiencing frequent connection problems. Not replacing your networking infrastructure may lead to business process disturbances, especially when you have several devices and servers connected to the network.

Don’t wait for a disaster to strike before you think about replacing your computer hardware and networking systems.

Servers and Storages

Hard drives

On average, hard drives last about four years. Usage, interface, and type play a role in how long a hard drive will last. You’ll know it’s time to replace your hard drive when it starts to slow down your computer. Say your computer hardware and networking systems frequently freeze up: that’s a sure sign that you have hard drive problem. Another sign that you should start thinking about replacing your hard drive is when you’re getting a lot of corrupted data. Not replacing your hard drive puts you at risk of losing your data and not being able to recover important data.

Servers

Onsite data servers are major investments, which is why some companies prefer to repair them rather than replace them. A server’s life span depends on workload and maintenance. It’s time to think about replacing your servers when it’s beyond the average service life. The older your server, the more maintenance cost it’ll require. It’s better to put your money in a cloud-based server, which requires less maintenance.

Computers

Computers

Desktops and laptops have an average life span of three to five years. However, there are many factors that affect the performance –and ultimately, the longevity – of your equipment. Poor ventilation may lead to overheating. This can damage components and slow down your system as heat builds up. Dust also prevents heat from leaving through the air vents. Using a computer that’s prone to overheating puts you at risk of losing important files and documents. Software updates may also cause your computer to slow down. Old computer hardware and networking systems with outdated operating systems may not be compatible with the latest software changes, which render them obsolete. Your old computer may still be working but if there are significant changes in performance, it may be time to get a new one.
