A guide to internet security
Whilst the overall benefits of using connected technology are huge, security is an understandable concern. Certain risks are inherent to regularly using the internet. But this should by no means put us off embracing digital in our roles as councillors.
That said, it’s important to be mindful of how we handle our devices, software and online accounts, how potentially sensitive information is shared digitally through those channels, and what responsible steps and precautions we should take to prevent online attacks or security breaches where possible.
What you will learn in this guide:
- what internet security is and some and the most common forms of ‘cyber attacks’
key steps you should take to protect yourself and your community, online
What is internet security and the most common online attacks?
Internet security describes the efforts and precautions we take to keep ourselves safe from malicious online attacks — which usually involve some kind of illegal breach of our web accounts, programs or connected devices.
Some of the most common types of so-called cyber attacks we should all be aware of include:
- Hacks: This basically describes the unauthorised access to a secured system by individuals or groups, commonly referred to as ‘hackers’. Common targets of hackers are websites, email accounts and large commercial or public databases.
- Phishing scams: One of the most common (and easy to fall for) form of online scam, this is where an individual (usually a hacker) masquerading as an established company such as a bank or well-known retailer, emails individuals asking them to hand over private data such as their email login or bank details. The scammer masquerades under some kind of bogus premise (such as ‘we need to update your details’ or ‘we’re updating our systems and need you to complete this form’). At first glance, these emails can be pretty convincing and it’s not hard to see how so many people can fall foul of them.
- Viruses: computer viruses are one of the longest and well-known of computer pests. They are essentially files or mini programs that can ‘sneak’ onto computers within wider files downloaded by users, with malicious intent — ranging from significantly slowing down your computer, to spying on or even controlling your computer, and extracting sensitive information for personal gain.
How to stay safe: top internet security tips
- Always use antivirus software: This is an absolute essential if you want to avoid having your devices compromised. There’s a range of options out there at various price points — but you needn’t fork out a fortune to protect your computer. There are actually quite a few cheaper or even free antivirus programs out there that are rated highly, and these days both Microsoft and Apple offer built-in protection with many of their devices. Mobile security shouldn't be overlooked either. Apps such as Lookout, can help protect your phone.
- Never trust unfamiliar email addresses or links: If you receive an email address out of the blue from a bank or retailer that asks for any personal details, treat it with extreme caution. A tell-tale sign of a phishing hack is that the email address (whilst in many cases can be impressively similar to the genuine brand’s) won’t be the real thing. If you suspect malicious intent, report the address to your email provider and delete. Phishing attacks and scams are becoming increasingly common on social media, too. Quite simply, if you don’t trust a link, never click on it.
- Secure your web browsers: All the common web browsers (Internet Explorer, Mozilla Firefox and Google Chrome) will have various security setting that can help minimise risk to your online accounts and data. For instance, you could switch off the option for your browser to remember your login details for email accounts and social media, set the security options to ‘high’ and regularly clear the browser’s cache (or even disable all together) so that your browser doesn’t cling on to too much potentially sensitive data.
- Regularly change your passwords: Make a rule to update all your passwords every few weeks. This might seem like a hassle, but if it significantly reduces risk of hacks and security breaches (which it does) then it’s worth the effort. Make sure you opt for a memorable yet secure password (many accounts advise on the quality of your selected password).
- Regularly update your software: This is a really basic one, but many people tend to ignore alerts from programs advising them to update to their latest version as ‘there are more important things to be getting on with’. However, the exact reason for many software updates can be to strengthen a recent security vulnerability.
- Always check site security levels before trusting: We often need to enter personal details on a website. As a general rule of thumb, all websites that ask for these details should be using an additional level of security to protect your data via an ‘https’ address (the ‘s’ stands for ‘security’ and websites that don’t have this, will be missing the ‘s’).
- Use common sense: At the end of the day, the reality of online security threats are not much different to the offline world. Simply be alert to unusual behaviour or practices, don’t trust strangers and be wary of unsolicited approaches for your information.
The internet, just like the ‘real’ world, is full of both potential opportunities, as well as dangers and risks. Hopefully this guide has made you aware of what those risks are and the steps that both you and your community should be taking to avoid becoming a target of cyber attacks.
