For everyday users, the most useful first steps are to use strong, unique passwords with a password manager, turn on multifactor authentication (MFA), install supported software updates promptly, and recognize and report phishing. If ransomware or an account compromise is already involved, preparation matters—but the guidance cited here does not establish a complete response sequence for an individual incident.
What is cybersecurity?
The Cybersecurity and Infrastructure Security Agency (CISA) defines cybersecurity as “the art of protecting networks, devices, and data from unlawful access or criminal use, and providing confidentiality, integrity, and availability of information.” The three goals mean keeping information private, keeping it accurate and trustworthy, and ensuring authorized people can access it when needed. CISA Cybersecurity 101 Tip Sheet (2022)
For a personal user, that can mean protecting an email account, phone, home network, or cloud-stored files. The same basic practices help reduce common risks, but no single measure guarantees that an account or device cannot be compromised.
What is phishing?
Phishing is a deceptive message, link, or attachment intended to get someone to disclose information or take a harmful action. It may imitate a familiar organization or person, but a convincing appearance is not proof that a message is legitimate. CISA recommends recognizing and reporting suspicious messages through appropriate channels. CISA Secure Our World: Turn On MFA

- Be cautious when a message unexpectedly asks you to sign in, share sensitive information, open an attachment, or act urgently.
- Do not use a message’s link or attachment simply because the sender name looks familiar; verify the request through a separate, trusted route.
- Report suspicious messages using the channel provided by your email service, workplace, school, or other relevant organization.
How do I protect my accounts?
CISA’s consumer-facing essentials emphasize strong passwords, a password manager, MFA, timely software updates, and recognizing and reporting phishing. CISA Secure Our World: Turn On MFA and CISA Four Cybersecurity Essentials for SLTTs (August 29, 2025)
Use strong, unique passwords
Use a different strong password for each account. Reusing one password means a password exposed in one breach could put other accounts at risk. A password manager can help create and keep track of unique credentials; the cited guidance supports the practice, not a particular vendor. CISA Secure Our World: Turn On MFA
Turn on MFA
MFA adds a verification step beyond your password. Turn it on wherever a service offers it, and select the strongest option that the service supports. The available methods and compatibility depend on the account and device. CISA Secure Our World: Turn On MFA
Install supported updates promptly
Keep your operating system, apps, browsers, and other supported software up to date. Updates can address security weaknesses; CISA includes timely software updates among its core essentials. CISA Four Cybersecurity Essentials for SLTTs (August 29, 2025)

What is MFA, and which method should I choose?
MFA—multifactor authentication—requires an additional verification step beyond a password. CISA advises using it broadly and choosing the strongest method a service supports. Its 2025 guidance identifies a physical security key as the preferred option among the methods listed below and says it offers the best phishing protection of those options. A key is not guaranteed to work with every account or device, so check service and device compatibility before choosing one. CISA Four Cybersecurity Essentials for SLTTs (August 29, 2025)
| MFA method | Phishing resistance | Ease of use | Compatibility to check |
|---|---|---|---|
| Physical security key | CISA calls this the best phishing protection among the methods listed in its 2025 fact sheet. | Requires having the key available when signing in. | Confirm the account and device support the key; compatibility is not universal. |
| Authenticator app with number matching | CISA lists this as an MFA option; the cited fact sheet ranks the physical key as providing the best phishing protection among the listed choices. | Requires access to the enrolled authenticator app and completion of its prompt. | Check that the service offers this method and the device can run the app. |
| Authenticator app with one-time codes | CISA lists this as an MFA option; the cited fact sheet ranks the physical key as providing the best phishing protection among the listed choices. | Requires access to the authenticator app and entering a code at sign-in. | Check service support and access to the enrolled app. |
The comparison reflects the options and guidance in CISA’s 2025 fact sheet, not a claim that every service implements them identically. If a physical key is unavailable or unsupported, using another MFA method is preferable to leaving MFA turned off. CISA Four Cybersecurity Essentials for SLTTs (August 29, 2025)
Why should I update my software?
Software updates can address security weaknesses, so unsupported or outdated software may leave known vulnerabilities uncorrected. Install supported updates promptly for the software you use. CISA includes current software among its cybersecurity essentials and recommends keeping software current in the context of ransomware resilience.

How can I prepare for ransomware?
Ransomware can disrupt access to files or systems. CISA recommends offline backups and a recovery plan, alongside keeping software current. Backups can help with recovery, but they do not prevent every compromise. The guidance supports the principles below rather than choosing a specific consumer product. CISA #StopRansomware Guide
Best Value
- Keep a backup copy offline. A copy that is disconnected from the affected device or network may remain available if that environment is compromised. A physical external drive is one possible way to keep an offline copy, but the recommendation is the backup principle, not a specific drive.
- Make a recovery plan. Decide how you would restore important data and regain access, and make sure the backup is recoverable rather than assuming that a copy exists and will work.
- Keep software current. Apply supported updates as part of preparation.
What should I do if I get ransomware?
The cited CISA guidance supports preparing with offline backups, a recovery plan, and current software. It does not establish a complete, authoritative step-by-step response for an individual whose device is infected. Avoid relying on a generic sequence for actions such as changing passwords from a potentially affected device, contacting a particular agency, or deciding whether to pay. Use the affected service’s official guidance and seek appropriate local or organizational support for the incident.
What do I do next if an account is hacked?
A detailed, authoritative recovery sequence for a compromised personal account is not established by the cited guidance here. Start with the affected service’s official account-recovery process, and contact appropriate organizational support if the account is managed by work, school, or another institution. Do not assume that a device potentially involved in the compromise is safe for sensitive recovery steps.
What do the cybersecurity survey numbers show?
CISA’s Cybersecurity Awareness Month 2024 Toolkit Guide relays figures from the National Cybersecurity Alliance’s 2023 Oh Behave! report. These are survey findings from 2023, not current population estimates or universal behavior. CISA Cybersecurity Awareness Month 2024 Toolkit Guide
| Survey finding | Share |
|---|---|
| Considered online safety a priority | 84% |
| Used unique passwords for all accounts | 38% |
| Were familiar with multifactor authentication | 79% |
| Always installed software updates when available | 36% |
| Expressed confidence in identifying phishing attempts | 69% |
| Actively reported cybercrimes, particularly phishing | 51% |
Each percentage is attributed to the National Cybersecurity Alliance’s 2023 report as relayed by CISA’s 2024 toolkit; the source does not make these figures current rates for all people.
