Which of the Following Is Best Practice for Physical Security

The best-practice answer shown across the physical-security results

The safest way to answer this question is to look for the choice that supports controlled access, clear identification, or reporting a concern. The results tied to DoD Cyber Awareness and physical security flashcards repeatedly point to these behaviors:

• Report suspicious activity.
• Wear your security badge.
• Use your own access credentials.
• Badge into the facility separately when entering with another coworker.

These examples all protect the same basic idea: people should be able to tell who belongs in a facility, and each person should use their own approved way to enter.

There isn't one universal answer choice across every flashcard result. Some versions ask about badges. Others focus on reporting activity or entering with a coworker. So don't memorize one sentence and ignore the wording. Match the choice on your quiz to the practice category it represents.

For a question asking, “Which of the following is a best practice for physical security?”, a choice about reporting suspicious activity is a strong answer when it appears. A choice about wearing a badge or using your own credentials also fits the recurring best-practice examples.

Why reporting suspicious activity is a recommended response

Reporting suspicious activity is presented as a physical-security best practice in the DoD Cyber Awareness material. The key point is simple: if something seems unusual or unsafe, don't ignore it.

This might appear in a question as a choice about reporting suspicious behavior, a concern near a facility, or activity that doesn't look right. The exact wording can change, but the expected action stays the same: report the concern through the proper channel named in the question or training material.

For exam purposes, don't confuse reporting with investigating. The answer isn't usually asking you to challenge someone, follow them, or handle the situation yourself. If one option says to report suspicious activity and another suggests ignoring it, reporting is the security-minded choice shown in the results.

That makes this a useful memory cue:

> See something suspicious? Report it.

Badge use, individual entry, and access credentials

Several recurring answer choices deal with visible identification and personal access.

Wear your badge

Wearing a security badge at all times is identified as a physical-security best practice. A badge helps show that a person has an accepted connection to the facility. It also makes it easier to notice someone who may not belong there.

If the choices include wearing your security badge, that option fits the confirmed pattern from the results.

Use your own credentials

Using your own access credentials is another repeated best practice. Your credentials are tied to you, so using them keeps entry connected to the right person.

A choice that suggests sharing, borrowing, or using someone else's access information should raise concern. The provided results specifically support using your own access credentials, not treating access information as something coworkers can swap.

Badge in separately from a coworker

One result gives a more specific example: when entering with another coworker, badge into the facility separately.

This may seem slower than following someone through the entrance, but the answer is testing individual access. Each person should use their own badge rather than entering under another person's access event.

So if a flashcard asks for the best practice when entering with a coworker, look for the option that says each person badges in separately.

How controlled access applies when entering a facility

Controlled access means entry is managed rather than treated like an open doorway. The recurring examples connect this idea with badges, credentials, and individual entry.

A question may use less direct wording. For example, one result includes holding the door for coworkers you know as an answer choice connected with controlled access. That wording is why you need to read the entire question and compare every option.

The flashcard snippets don't clearly label that choice as the single correct answer in every version. They show it as part of the answer-choice variation. Don't automatically treat “coworker you know” as permission to skip individual badging.

For a quiz, give more weight to choices that clearly say:

• Use your own credentials.
• Badge in separately.
• Keep your security badge visible or worn.
• Report suspicious activity.

Those choices state the security action directly. A choice about holding a door may depend more on how the question frames controlled access.

What to do when someone is not wearing a badge

Approaching unknown people without badges is shown in the results as a concerning option, not as a recommended practice. This is an important distinction for questions asking which action is not a best practice.

The concern is the lack of clear identification. Someone you don't recognize who isn't wearing a badge should not be treated as automatically authorized simply because they are inside or near an entrance.

The exam wording may present this as an action involving an unknown person without a badge. If so, that choice should stand out as the one that does not fit the confirmed best-practice pattern.

Be careful with the wording, though. The supplied flashcard results don't provide one complete response procedure for every situation. They support recognizing the behavior as a security concern. They do not support adding extra steps that aren't listed in the question.

Physical-security choices that should raise concern

The easiest way to sort confusing choices is to separate recommended behaviors from warning signs.

Behaviors shown as best practices

These appear repeatedly in the physical-security results:

• Reporting suspicious activity.
• Wearing a security badge.
• Using your own access credentials.
• Badging into the facility separately from a coworker.

Each one supports identification, accountability, or controlled entry.

Behaviors framed as concerns

Other answer choices are presented as questionable or concerning, including:

• Approaching unknown people who aren't wearing badges.
• Entering with someone else instead of using your own badge.
• Treating a coworker's access as a substitute for your own credentials.

The last two points describe the risk behind the answer choices. The exact flashcard wording may differ, so use them as patterns rather than as a copied answer.

One detail can make a big difference: knowing a coworker and using your own credentials are not the same thing. A person may be familiar to you, but the results still point toward individual badging and personal access credentials.

How to approach this question on the Cyber Awareness exam

For Cyber Awareness 2026 or a similar DoD knowledge check, start by identifying what the question is testing. Is it asking about:

1. Reporting something suspicious?
2. Wearing or checking a badge?
3. Using personal access credentials?
4. Entering a controlled facility with another person?

Then choose the option that clearly supports that principle.

Quick practice questions

#### Which of the following is a best practice for physical security in DOD cyber?

The likely answer depends on the choices shown. The recurring correct behaviors are reporting suspicious activity, wearing a security badge, using your own access credentials, and badging in separately when entering with a coworker.

#### What is the best practice for physical security?

Look first for an option about reporting suspicious activity. If that isn't listed, check for wearing a badge, using your own credentials, or maintaining controlled access through separate badging.

#### Which of the following is not a physical-security best practice?

A choice about approaching unknown people without badges is presented as a concern. Choices that support wearing a badge, using personal credentials, and reporting suspicious activity fit the recommended pattern.

The reason flashcard answers seem to conflict is that different versions use different slices of the same topic. One may focus on reporting. Another may focus on entry. A third may list badge-related choices. Compare the exact options in front of you instead of relying on one isolated “physical security flash” answer.

Before selecting an answer in the Cyber Awareness knowledge check, match the choices to the three main categories: controlled access, badges and credentials, and reporting suspicious activity. Then compare that category with the exact wording on your screen.
