- Building long-term cybersecurity habits
Follow these best practices and dramatically lower your risks.
Why Personal Cybersecurity Matters
In 2022 alone, over 847 million records were exposed in data breaches, says Tenable. And those are just reported incidents – many more likely go undiscovered.
Beyond big hacks making headlines, individuals face a gauntlet of threats like:
- Account takeovers: Criminals seize control of online accounts through compromised login credentials. Once inside, they can steal data, lock you out entirely and abuse access further.
- Financial fraud: Bank details, credit cards and funds get stolen, costing tremendous time and money to remedy.
- Ransomware: Malware encrypts your data until you pay the perpetrators.
- Identity theft: Leveraging pieces of exposed information, criminals impersonate victims to open accounts, file taxes and worse.
And that‘s not even considering privacy erosion from rampant data collection/sharing.
Without proper personal cybersecurity in place, almost every adult internet user will suffer an average of 21 cybercrime incidents annually at a cost of $375 billion by 2025, predicts Cybersecurity Ventures.
You must tackle this rising risk through disciplined vigilance – the tips below show you how.
Securing Online Accounts
Accounts like email, social platforms and banking represent gateways into your digital life. Compromised login credentials can spiral into many other breaches.
Follow these rules of thumb for all web and mobile app accounts:
Use Strong, Unique Passwords
The 2023 Verizon Data Breach Report reveals over 80% of hacking breaches involved brute forced or stolen passwords. Weak, reused credentials remain prevalent despite well-known risks.
Best practices include:
- 8+ random characters mixing upper/lowercase, numbers and symbols
- Avoid dictionary words, names, places or dates
- Absolutely no reuse across accounts
- Change quarterly at minimum
Manually tracking unique, complex passwords for every account is unrealistic. That‘s why password managers like LastPass and 1Password are vital. These tools securely store strong credentials and enter them automatically during login.
Enable password manager autofill whenever possible to prevent exposing passwords through phishing.
"Most people use bad passwords even though they know better – the average person types 8 passwords per day and struggles to keep them secure." – Inc.com
Tackling password problems systematically matters most, not periodic changes for their own sake.
Turn On Two-Factor Authentication (2FA)
Two-factor authentication checks two credentials before granting account access – what you know (password) and what you have (mobile device).
Even with the password, login fails without providing the unique single-use code generated on your phone/tablet.
According to Microsoft, 2FA stops 99.9% of automated cyberattacks and over 97% of targeted human hacking attempts. Enable it wherever you can including:
Important Accounts to Secure
- Banking
- Investment
- Shopping
- Social media
- Cloud storage
- Government portals
With accounts protected by strong 2FA, hackers face severely limited options to compromise credentials. They can infiltrate individual sessions once logged in but can‘t breach the gateway permanently.
Recognize and Avoid Phishing Attempts
Phishing deploys social engineering techniques through email, sites, ads and more to trick victims into disclosing login credentials or financial details themselves.
And phishing keeps getting craftier:
- 83% of organizations experienced phishing attacks in 2022 says Proofpoint.
- Phishing targets every industry from finance to tech to retails.
- Attacks grow more personalized, exploiting psychological triggers tailored to victims after reconnaissance.
Stay vigilant for telltale phishing signs:
Email Red Flags
- Grammatical/spelling errors
- Unknown sender address
- Threatening urgent action
- Suspicious attachments/links
- Requests sensitive information
Website Red Flags
- No HTTPS padlock icon
- Suspicious domain name
- Generic interfaces
- Password fields on odd pages
When unsure, access sites through official bookmarks rather than clicking direct links. Also beware of phishing attempts through ads and social media.
Enable email spam filtering, use secured browsers like Brave or Safari, avoid pirated software and don‘t share personal information freely.
Fake login pages are common phishing tactics. Always check the URL before entering credentials.
Securing Devices and Networks
Our computers, phones, smart home devices etc. house massive amounts of personal data – controlling device access prevents breach cascades.
Follow comprehensive guidelines below to lock environments.
Keep Software Patched and Updated
Unpatched software poses massive risk – bugs and flaws remain open for hackers to exploit before fixes arrive through updates.
Case in point – 2021‘s Windows PrintNightmare vulnerability enabling potential remote code execution went unpatched for weeks after public disclosure.
Prioritize patching:
- Operating systems – Windows, MacOS, ChromeOS, Linux distributions
- Web browsers – Chrome, Safari, Firefox etc.
- Productivity software – Microsoft Office, Adobe products
- Media players, compression utilities and runtimes like Java and Flash
Enable automatic background updates wherever possible. For faster rollout of urgent fixes, temporarily disable "defer updates" settings in Windows.
Reboot devices regularly to finalize installations pending restart.
While updating apps from official stores like Play Store and App Store, avoid enabling installation outside these trusted sources to prevent malware.
Install Security Software
Endpoint protection software like antivirus guards devices against malware, viruses, exploits and more threats trying to gain footholds within systems.
Top options like Avast, Norton and McAfee offer:
- Real-time scanning of device activity
- Malicious URL blocking
- Vulnerability assessments
- Firewall functionality
Ensure subscriptions don‘t lapse. Schedule periodic scans probing entire systems too.
While Windows Defender comes built-in, third-party alternatives catch 20% more threats according to Germany‘s AV-TEST labs.
Smartphone antivirus usefulness is contested – hence focus resources on securing desktops and laptops first.
Encrypt Data
Data encryption transforms information using algorithms requiring keys or passwords to decipher. Thus even if devices get physically compromised, data remains secured.
Encrypt devices using BitLocker on Windows or FileVault on Mac. Set device authentication requirements to further strengthen protection against unauthorized boot access.
For external media like USB drives, enable encryption setting provided by manufacturers. Open source tools like VeraCrypt allow encrypting drives for multi-OS support.
When disposing old device storage media, use multi-pass data overwriting software to permanently purge contents before recycling or reuse.
Wi-Fi Network Safety
Home and public Wi-Fi poses dangers from fake spoofing networks to man-in-the-middle attacks intercepting connections.
Improve home Wi-Fi safety by:
- Hiding network SSID
- Using latest WPA3 protocol
- Employing MAC address filtering
- Enforcing strong Wi-Fi password
For public networks, always use a VPN to encrypt connections. Free options like ProtonVPN and TunnelBear suffice. Connect via mobile hotspots when possible.
Never save passwords on public networks or auto-join unfamiliar open ones. Double check network names when connecting to prevent spoofing.
Backup Diligently
Data backups create restorable versions of files/systems – insurance against ransomware, device failures and accidental deletion.
Follow industry standard 3-2-1 backup strategy:
- 3 copies of data
- In 2 different storage formats
- With 1 copy off-site
Schedule regular backups instead of sporadic ones. Continuous cloud backup services like iDrive offer unlimited storage and sync capability.
Always keep 1 copy offline/off-site in case malware infiltrates live systems – encrypted external drives provide portable options.
Safeguarding Data Privacy
Beyond hacking risks, uncontrolled data also erodes privacy as trails of personal information get proliferated and monetized without consent.
Protect data through:
Securing Internet of Things (IoT)
Smart home speakers, mobile apps, wearables constitute booming Internet of Things (IoT) category. While delivering convenience, they also pose privacy issues with always-on microphones, cameras and multiple sensors.
Follow guidelines to manage risks:
- Disable unused IoT capabilities
- Put IoT on guest Wi-Fi instead of primary home network
- Use device data encryption when available
- Prevent IoT linking with contacts/social media without vetting
- Remove IoT no longer used – factory reset and unlink accounts
Always set up IoT using unique passwords given lax default settings from manufacturers.
Controlling Social Apps
Social platforms incentivize oversharing personal activities, locations and connections for revenue – often without true informed user consent on data usage despite agreeing to dense policies and terms nobody reads!
Exercise more discretion before posting to limit privacy erosion. Audit platforms using privacy checkers like Privacy Bee to tune visibility settings.
Managing Web Privacy
- Employ ad blockers like uBlock Origin foiling trackers
- Use privacy-focused browsers like Brave and Firefox blocking online tracking
- Disable unused browser plug-ins and extensions
- Clear caches and browsing history regularly
- Mask IP address through trustworthy VPNs like ExpressVPN
Below Firefox settings enhance anti-tracking and fingerprint protection:
Understanding Data Policies
- Read privacy policies on websites/apps instead blindly accepting
- Adjust app permissions conscientiously
- Check bank/utility privacy statements on selling data
- Opt out of data sharing wherever possible
- Consider paying for apps offering better privacy
Building Long-Term Cybersecurity Habits
Cultivating consistent cybersecurity habits for the long run matters more than sporadic mitigations.
Focus on gradually implementing basics before trying advanced protections. Baby steps create lasting change.
Start with Foundations
- Use password manager for all accounts
