Cyber Safety and Security: Practical Steps to Protect Yourself Online
We use the internet to communicate, shop, work, study and manage our finances. These everyday activities can expose personal information and devices to risks such as scams, malicious software and account theft. Good cyber safety is not about avoiding the internet; it is about making informed choices and taking a few practical steps to reduce those risks.
Use strong, unique passwords
A password that is reused across several accounts can put all of them at risk if one service is breached. Use a different password for each important account, especially email, banking and social media. A reputable password manager can generate and store long, unique passwords, so you do not have to memorise them all.
Where available, turn on multi-factor authentication (MFA). This asks for an additional check when you sign in, such as an approval through an authenticator app or a security key. It can make an account harder to access even if someone learns your password.
Be cautious with messages and links
Phishing messages try to persuade you to reveal information, send money or open a harmful link or attachment. They may appear to come from a bank, delivery company, employer or someone you know. Watch for unexpected requests, pressure to act quickly, unfamiliar sender addresses and links that do not match the organisation’s official website.
If a message asks you to sign in or make a payment, avoid using its link. Instead, visit the organisation’s website or app directly, or contact it using details you have checked independently. Never share passwords or one-time security codes with someone who contacts you unexpectedly.
Keep devices and software up to date
Updates often include fixes for security weaknesses. Turn on automatic updates for your operating system, browser, apps and security software where possible. Remove apps and browser extensions you no longer use, and download software only from trusted sources.
Use a screen lock and a PIN or password on phones, tablets and computers. If a device offers encryption, keep it enabled, particularly if you store sensitive information on it.
Protect your home and public connections
Change your router’s default administrator password and use a strong Wi-Fi password. Keep the router’s software up to date and use modern encryption settings where available. If you use public Wi-Fi, be careful when accessing sensitive accounts; a mobile data connection may be a better choice for banking or other important transactions.
Back up important information
Backups can help you recover from device failure, accidental deletion or a cyberattack. Keep copies of important files in a secure cloud service or on an external drive. If you use an external drive, disconnect it when the backup is complete so it is less exposed to malware or unauthorised access. Check occasionally that you can restore your files.
Think carefully about what you share
Personal details shared online can be used in scams or to guess security questions. Review the privacy settings on social media and other accounts, and consider who can see your posts. Be cautious about sharing your address, travel plans, financial details or information that could help someone impersonate you.
Know what to do if something goes wrong
If you think an account has been compromised, change its password using the official website or app, sign out of other sessions if that option is available, and check the account’s recovery details. If the same password was used elsewhere, change it on those accounts too. Contact your bank promptly if you notice an unfamiliar payment, and report suspicious messages through the relevant service.
If a device behaves unusually, avoid entering passwords or financial details on it until you have checked it. Use trusted security software or seek help from a reputable support provider. Be wary of unsolicited callers or pop-up messages claiming your device is infected and demanding payment or remote access.
Make cyber security a habit
No single tool can prevent every threat, but regular updates, unique passwords, MFA, careful handling of messages and reliable backups can significantly improve your protection. Take a moment to check before clicking, sharing information or approving a sign-in request. Small, consistent habits can make online life safer for you and the people around you.

Protects personal information from theft.
Cyber safety and security help protect personal information from theft by making it harder for criminals to access details such as passwords, banking information and contact details. Using strong, unique passwords, enabling multi-factor authentication and being cautious with suspicious messages can reduce the risk of accounts being compromised. Keeping this information secure helps prevent identity fraud, unauthorised purchases and other forms of misuse.
Helps prevent unauthorised account access.
Strong cyber safety practices help prevent unauthorised access to your online accounts. Using a unique, hard-to-guess password for each account and enabling multi-factor authentication makes it much more difficult for someone to sign in, even if they obtain one of your passwords. Being cautious with unexpected links and never sharing security codes adds another layer of protection for your personal information.
Reduces the risk of online scams.
Good cyber safety habits can reduce the risk of falling victim to online scams. Checking who has sent a message, avoiding unexpected links and verifying payment requests through official channels can help you spot phishing attempts and fake offers before sharing personal details or money. Using strong, unique passwords and multi-factor authentication also makes it harder for scammers to access your accounts.
Keeps devices safer from malware.
Good cyber safety habits help keep devices safer from malware, including viruses, spyware and ransomware. Installing updates promptly, using reputable security software and downloading apps only from trusted sources can reduce the chance of harmful programmes getting onto your phone or computer. Being cautious with unexpected links and attachments also helps prevent malware from spreading, protecting your files, personal information and the smooth running of your devices.
Protects financial details when shopping online.
Cyber safety helps protect your financial details when shopping online. Using secure websites, strong unique passwords and multi-factor authentication can make it harder for criminals to access your accounts or misuse your card information. Staying alert to fake shops, suspicious links and unexpected payment requests also helps you shop with greater confidence and reduce the risk of fraud.
Supports safer internet use for families.
Cyber safety and security help families use the internet with greater confidence. Parental controls, privacy settings and age-appropriate guidance can help children avoid unsuitable content, online scams and unwanted contact, while strong passwords and account protection safeguard the whole household’s personal information. By talking openly about online risks and practising safe habits together, families can enjoy the benefits of the internet while reducing potential harm.
Helps prevent data loss with regular backups.
Regular backups are an important part of cyber safety because they help protect your files if a device is damaged, lost, infected with malware or affected by accidental deletion. Keeping up-to-date copies in a secure cloud service or on an external drive means you can restore valuable documents, photos and other information instead of losing them permanently. For extra protection, keep an external backup disconnected when it is not in use, and check periodically that your files can be restored.
Builds confidence when using digital services.
Good cyber safety and security help people feel more confident when using digital services. Knowing that personal information and accounts are protected makes it easier to shop online, use banking apps, communicate and access essential services. Simple measures such as strong passwords, multi-factor authentication and secure connections can reduce the risk of fraud or data theft, giving people greater peace of mind as they go about their digital lives.
Strong passwords can be difficult to remember.
One drawback of strong passwords is that they can be difficult to remember, particularly when every account has a different, lengthy combination of letters, numbers and symbols. This may tempt people to reuse passwords or choose simpler ones, which can weaken security. A reputable password manager can help by securely storing unique passwords, while multi-factor authentication adds an extra layer of protection.
Multi-factor authentication can add extra sign-in steps.
Multi-factor authentication (MFA) adds an extra layer of protection, but it can make signing in less convenient. You may need to enter a code, approve a notification or use a security key each time you access an account, which can take longer—particularly when you are in a hurry or do not have your phone to hand. If your chosen verification method is unavailable, getting back into your account may also be more complicated.
Security software may require a subscription.
Some security software requires a paid subscription, which can add to the cost of using a computer or mobile device. Essential features such as real-time protection, parental controls or identity monitoring may only be available on a premium plan, and subscriptions often renew automatically. Before signing up, check the renewal price, cancellation terms and which features are included, and compare them with the protection already provided by your device.
Updates can interrupt work or use mobile data.
Software updates can interrupt work, particularly when a device restarts or an installation takes longer than expected. Updates downloaded over a mobile connection may also use a significant amount of data, which can be costly if your plan has a limited allowance. Where possible, schedule updates for a convenient time and download them over a trusted Wi-Fi connection.
Privacy settings can be confusing to manage.
Privacy settings can be confusing to manage, particularly when each app, website and device uses different menus and options. Important controls may be difficult to find, and changes to a service can reset or alter existing preferences. As a result, people may share more personal information than they intend to, or believe they are protected when certain details remain visible. Reviewing settings regularly and checking who can access your information can help, but it takes time and attention.
Backups need regular checks and storage space.
Backups are only useful if they work when you need them, so they need to be checked regularly to make sure files are being saved correctly and can be restored. They also require enough storage space, which may mean deleting old files, buying an external drive or paying for additional cloud storage. Without routine checks and room for new data, backups may be incomplete or out of date when a device fails or an attack occurs.
