What Is The Difference Between A False Positive And A False Negative In Ids
- A false positive is considered to be a false alarm and a false negative is considered to be the most complicated state.
- A false positive occurs when an IDS fires an alarm for legitimate network activity.
- A false negative occurs when IDS fails to identify malicious network traffic.
Compared to both, a false positive is more acceptable than a false negative as they lead to intrusions without getting noticed.

What Do You Understand By Port Scanning
Port scanning is the technique administrators, and hackers use to identify the open ports and services available on a host. Hackers use this technique to find information that can be helpful to find flaws and exploit vulnerabilities, and administrators use this technique to verify the security policies of the network.
Following is a list of some most common Port Scanning Techniques:
- Stealth Scanning

How To Prevent Csrf Attacks
CSRF is referred to as Cross-site Request Forgery, where an attacker tricks a victim into performing actions on their behalf.
CSRF attacks can be prevented by using the following ways:
- Employing the latest antivirus software which helps in blocking malicious scripts.
- While authenticating to your banking site or performing any financial transactions on any other website do not browse other sites or open any emails, which helps in executing malicious scripts while being authenticated to a financial site.
- Never save your login/password within your browser for financial transactions.
- Disable scripting in your browser.

What Is An Active Reconnaissance
- Active reconnaissance is a kind of computer attack where an intruder engages the target system for collecting data about vulnerabilities.
- The attackers mostly use port scanning to identify vulnerable ports and then exploit the vulnerabilities of services that are associated with open ports.

Explain Social Network Phishing
Phishing is a cybercrime technique in which attackers disguise fraudulent communications as legitimate or trustworthy in order to steal sensitive data or install malware on a targets device. Social network phishing, sometimes also referred to as angler phishing, harnesses notifications or messaging features on social media to lure targets.
You Receive An Email From Your Bank Telling You There Is A Problem With Your Account The Email Provides Instructions And A Link So You Can Log Into Your Account And Fix The Problem
What should you do?
Delete the email. Better yet, use the web client and report it as spam or phishing, then delete it.
Any unsolicited email or phone call asking you to enter your account information, disclose your password, financial account information, social security number, or other personal or private information is suspicious even if it appears to be from a company you are familiar with. Always contact the sender using a method you know is legitimate to verify that the message is from them.

Top Cybersecurity Project Manager Interview Questions
So what questions can you expect in a cybersecurity project manager job interview?
Here’s a list of common questions:
38. Q: What is a data leak? How can you detect it and prevent it?
A:A data leak is when a company’s or organization’s private data is released to the public in an unauthorized manner. Data leaks can come in many ways such as hacked emails and networks, stolen or lost laptops, or released photos.
To prevent a data leak, a company needs to restrict internet uploads, add restrictions to email servers, and restrict the printing of confidential information and data.
To detect a data leak, you’ll need to:
1) Monitor access to all your networks
2) Evaluate the risk of third-parties
3) Identify and secure sensitive data
4) Encrypt data
6) Evaluate permissions across the organization
7) Use cybersecurity risk assessments
39. Q: What is a cybersecurity risk assessment?
A:A cybersecurity risk assessment is part of an organization’s risk management strategy because it helps them see how their security is performing along with current vulnerabilities and potential risks.
A cybersecurity risk assessment also covers the different types of assets owned by a company that may be prone to cyberattacks. These assets can include physical assets such as hardware, laptops, or non-physical assets such as customer data.
Companies that use a cyber risk assessment can prioritize addressing those risks based on their importance and the available budget.

Q: What Is Vlan And What Are The Differences Between A Vpn And A Vlan
A:The VPN is a remote access network with an encrypted and secured tunnel. A VPN prevents hackers from accessing the network and doesn’t allow people to capture the data packets.
Meanwhile, the virtual LAN is a broadcast domain that is isolated within a computer network at the data link layer. Using a VLAN, we can group work stations that aren’t found in the same location as the broadcast network. A VLAN doesn’t require or involve encryption and it can divide networks without physically segregating the switches.
Q: What Are The Differences Between Symmetric And Asymmetric Encryption And Which Is Better
Bonus Tip:This is a broad topic so keep your answer simple and to the point. You don’t want to lose the interviewer in unnecessary details.
A:Symmetric encryption is a type of encryption that uses a single key, a secret key, to both encrypt and decrypt electronic information. Entities communicating via symmetric encryption must exchange the key so they can be used in the decryption process.
On the other hand, Asymmetric encryption uses two keys, one public and one private, to encrypt and decrypt messages.
While the symmetric encryption is faster, the key needs to be transferred using an unencrypted channel, the asymmetric encryption is slower but more secure.
Each has its pros and cons, which means a better approach is to combine the two types of encryption. This means we’ll need to set up a channel with asymmetric encryption and send the data using a symmetric process.

In a Half-Duplex Mode, the data can be transmitted in two directions using a signal carrier. However, the transmission cannot be done in both directions at the same time.
In the Full-Duplex Mode, the data is bidirectional, that is, it can be sent in both directions at the same time.

Q: What Is Vulnerability Assessment And How Is It Different From Penetration Testing
A: Vulnerability Assessment is the process of locating flaws or vulnerabilities on the target. For example, a company may be aware that its security system has flaws or weaknesses. To find those flaws, prioritize them, and fix them, they would need to conduct a Vulnerability Assessment.
On the other hand, Penetration Testing is the process of finding vulnerabilities on the target. In this situation, the company would have set up all possible security measures they could think of and test other ways their system or network may be hacked.
