Your computer holds a wealth of personal and sensitive information, from account credentials to financial records. Protecting that information starts with a few practical habits that can keep you one step ahead of cyber threats. Whether you access your accounts on a portable laptop or a stationary desktop, having the right protective measures in place makes a meaningful difference. Here's how to get started.

Tips for Protecting Your Computer

A few foundational habits go a long way toward keeping your device secure. You can:

• Install anti-virus software and enable your firewall to identify and protect against cyber threats.
• Continuously update your operating system and all software to the most recent versions.
• Create strong passwords and use biometrics.
• Always lock your computer when it's unattended.
• Never provide remote access to your device.

Anti-Virus Software

Enabling anti-virus software can protect your computer by blocking unwanted pop-ups, malicious content, and phishing attempts. The software scans your device to locate potential threats and mitigate them. Just like your operating system, it's important to keep your anti-virus software up to date so it can effectively detect and remove threats.

Bad actors use different types of viruses to target your device. Some create visible changes while others live quietly and go unnoticed. Anti-virus software can detect these changes and remove them. The Cybersecurity and Infrastructure Security Agency (CISA) recommends installing antivirus software, firewalls, and email filters, and keeping them updated to reduce malicious network traffic.

Encryption

Computer encryption is an established method of protecting your device if a bad actor gains control of it. When encryption is enabled, your data is protected from being compromised, altered, or stolen. Encryption works by scrambling data into a secret code that can only be unlocked with your digital key.

If your device is lost or acquired by a bad actor, encryption prevents unauthorized access by making the data unreadable. CISA recommends encrypting all devices, hard drives, removable media, and relevant documents, both at rest and in transit.

Firewalls

Firewalls provide security for your computers and networks by preventing malicious content from entering your devices. They also block unauthorized access that might be initiated by a bad actor. Firewalls can give you an added layer of privacy, prevent spyware and hacking, stop virus attacks, and monitor your network traffic for signs of potential threats.

When your device is accessible through an internet connection or Wi-Fi network, it is susceptible to attack. However, you can restrict outside access with a firewall.

Staying Safe on Public Wi-Fi

Public Wi-Fi networks at coffee shops, airports, and hotels offer convenience, but they also introduce risks. When you connect to a network you don't control, your data could be exposed to others on that same network. While most websites now use encryption that protects the content of your browsing, certain threats remain:

• Fake hotspots designed to look legitimate
• Malicious portals that can intercept your information
• Network operators who can monitor your activity

A virtual private network (VPN) creates an encrypted tunnel between your device and a remote server, hiding your activity from the local network operator. Consider using a reputable VPN when you need to access sensitive accounts on public Wi-Fi.

For tasks that involve logging into financial accounts or entering personal information, switching to your cellular data connection may offer an added layer of protection.

A few simple habits can keep you safer on public networks:

• Verify the exact network name with staff before connecting.
• Avoid networks that don't require a password.
• Keep your operating system and browser up to date, as these updates often include security improvements.

Consider Backing Up Your Data

Another best practice for protecting your computers is to back up your data on a recurring basis. There are several options you can choose for data backup, and each has its own advantages.

Cloud Service

With cloud service, data and files are saved in a remote location through third-party vendors who provide space on their servers for storage. You can then access your data and files through multiple devices with the benefit of cross-platform accessibility. CISA recommends backing up data to a vetted cloud service or external hard drive and encrypting your backups.

Local Backup Options

For users who would rather opt out of cloud service, encrypted USB drives and external hard drives can be used to back up data. These options give you physical control over your backups and don't require an internet connection to access your files.

What to Do If Your Computer Is Compromised

If you suspect your computer is compromised, acting quickly can limit the damage. Take these steps:

• Disconnect your device from the internet to prevent further unauthorized access.
• Run a full scan with your anti-virus software to identify and remove any threats.
• Speak with a local IT professional to help confirm your device is secure.
• If you believe your financial accounts may have been affected, contact LPL Financial immediately.
• Review your recent account activity for any unauthorized transactions.
• Change your passwords and security settings.

You can also review your accounts through LPL Account View, which uses multi-factor authentication and biometrics to help protect your information.

Taking proactive steps to keep your computer safe can help you protect what matters most. By combining anti-virus software, encryption, firewalls, regular backups, and smart habits on public Wi-Fi, you can build a strong defense against cyber threats.
