Vulnerability Assessment is a process for defining, detecting, and prioritizing vulnerabilities in computer systems, network infrastructure, applications, and other systems, as well as providing the necessary information to the organization to correct the flaws.
Penetration Testing is also known as ethical hacking or pen-testing. It’s a method of identifying vulnerabilities in a network, system, application, or other systems in order to prevent attackers from exploiting them. It is most commonly used to supplement a web application firewall in the context of web application security (WAF).
A vulnerability scan is similar to approaching a door and checking to see if it is unlocked before stopping. A penetration test goes a step further, not only checking to see if the door is unlocked but also opening the door and walking right in.

Honeypots are decoy systems or servers deployed alongside production systems within your network. When deployed as enticing targets for attackers, honeypots can add security monitoring opportunities for blue teams and misdirect the adversary from their true target. Honeypots come in a variety of complexities depending on the needs of your organization and can be a significant line of defense when it comes to flagging attacks early. This page will get into more detail on what honeypots are, how they are used, and the benefits of implementing them.

• Businesses are protected from cyberattacks and data breaches.
• Both data and network security are safeguarded.
• Unauthorized user access is kept to a minimum.
• There is a quicker recovery time after a breach.
• Protection for end-users and endpoint devices.
• Regulatory compliance.
• Operational consistency.
• Developers, partners, consumers, stakeholders, and employees have a higher level of trust in the company’s reputation.

A sample firewall between a LAN and the internet is shown in the diagram below. The point of vulnerability is the connection between the two. At this point, network traffic can be filtered using both hardware and software.

There are two types of firewall systems: one that uses network layer filters and the other that uses user, application, or network layer proxy servers.

Vulnerability: A vulnerability is a flaw in hardware, software, personnel, or procedures that threat actors can use to achieve their objectives.
Physical vulnerabilities, such as publicly exposed networking equipment, software vulnerabilities, such as a buffer overflow vulnerability in a browser, and even human vulnerabilities, such as an employee vulnerable to phishing assaults, are all examples of vulnerabilities.
Vulnerability management is the process of identifying, reporting and repairing vulnerabilities. A zero-day vulnerability is a vulnerability for which a remedy is not yet available.

Risk: The probability of a threat and the consequence of a vulnerability are combined to form risk. To put it another way, the risk is the likelihood of a threat agent successfully exploiting a vulnerability, which may be calculated using the formula:

Risk = Likelihood of a threat * Vulnerability Impact

Risk management is the process of identifying all potential hazards, analyzing their impact, and determining the best course of action. It’s a never-ending procedure that examines new threats and vulnerabilities on a regular basis. Risks can be avoided, minimized, accepted, or passed to a third party depending on the response chosen.

Confidentiality

The information should be accessible and readable only to authorized personnel. It should not be accessible by unauthorized personnel. The information should be strongly encrypted just in case someone uses hacking to access the data so that even if the data is accessed, it is not readable or understandable.

Integrity

Making sure the data has not been modified by an unauthorized entity. Integrity ensures that data is not corrupted or modified by unauthorized personnel. If an authorized individual/system is trying to modify the data and the modification wasn’t successful, then the data should be reversed back and should not be corrupted.

Availability

The data should be available to the user whenever the user requires it. Maintaining of Hardware, upgrading regularly, Data Backups and Recovery, Network Bottlenecks should be taken care of.

Solution 1

Several people misread this as a question about how to store passwords in a database. That is wrong. It is about how to store the password that lets you get to the database.

The usual solution is to move the password out of source-code into a configuration file. Then leave administration and securing that configuration file up to your system administrators. That way developers do not need to know anything about the production passwords, and there is no record of the password in your source-control.

Solution 2

If you’re hosting on someone else’s server and don’t have access outside your webroot, you can always put your password and/or database connection in a file and then lock the file using a .htaccess:

<files mypasswdfile>
order allow,deny
deny from all
</files>

Solution 1

The current cookie specification is RFC 6265, which replaces RFC 2109 and RFC 2965 (both RFCs are now marked as “Historic”) and formalizes the syntax for real-world usages of cookies. It clearly states:

For historical reasons, cookies contain a number of security and privacy infelicities. For example, a server can indicate that a given cookie is intended for “secure” connections, but the Secure attribute does not provide integrity in the presence of an active network attacker. Similarly, cookies for a given host are shared across all the ports on that host, even though the usual “same-origin policy” used by web browsers isolates content retrieved via different ports.

Weak Confidentiality

Cookies do not provide isolation by port. If a cookie is readable by a service running on one port, the cookie is also readable by a service running on another port of the same server. If a cookie is writable by a service on one port, the cookie is also writable by a service running on another port of the same server. For this reason, servers SHOULD NOT both run mutually distrusting services on different ports of the same host and use cookies to store security sensitive information.

I have two separate files: certificate (.cer or pem) and private key (.crt) but IIS accepts only .pfx files.

I obviously installed certificate and it is available in certificate manager (mmc) but when I select Certificate Export Wizard I cannot select PFX format (it’s greyed out)

Are there any tools to do that or C# examples of doing that programtically?

Solution 1 :

You will need to use openssl.

openssl pkcs12 -export -out domain.name.pfx -inkey domain.name.key -in domain.name.crt

The key file is just a text file with your private key in it.

If you have a root CA and intermediate certs, then include them as well using multiple -in params

openssl pkcs12 -export -out domain.name.pfx -inkey domain.name.key -in domain.name.crt -in intermediate.crt -in rootca.crt

If you have a bundled crt file that you use, for example, with nginx, you can pass that in along with the cert all in one:

cat domain.name.crt | tee -a domain.name.bundled.crt
cat intermediate.crt | tee -a domain.name.bundled.crt
cat rootca.crt | tee -a domain.name.bundled.crt
openssl pkcs12 -export -out domain.name.pfx \
  -inkey domain.name.key \
  -in domain.name.bundled.crt 

How much of HTTPS headers are encrypted?

Including GET/POST request URLs, Cookies, etc.

Solution 1:

The whole lot is encrypted^† – all the headers. That’s why SSL on vhosts doesn’t work too well – you need a dedicated IP address because the Host header is encrypted.

^†The Server Name Identification (SNI) standard means that the hostname may not be encrypted if you’re using TLS. Also, whether you’re using SNI or not, the TCP and IP headers are never encrypted. (If they were, your packets would not be routable.)

$unsafe_variable = $_POST['user_input']; 

mysql_query("INSERT INTO `table` (`column`) VALUES ('$unsafe_variable')");

That’s because the user can input something like value'); DROP TABLE table;--, and the query becomes:

INSERT INTO `table` (`column`) VALUES('value'); DROP TABLE table;--')

What can be done to prevent this from happening ?

Solution 1

You basically have two options to achieve this:

1. Using PDO (for any supported database driver):

$stmt = $pdo->prepare('SELECT * FROM employees WHERE name = :name');

 $stmt->execute([ 'name' => $name ]);

 foreach ($stmt as $row) {
     // Do something with $row
 }


2. Using MySQLi (for MySQL):

$stmt = $dbConnection->prepare('SELECT * FROM employees WHERE name = ?');
 $stmt->bind_param('s', $name); // 's' specifies the variable type => 'string'

 $stmt->execute();

 $result = $stmt->get_result();
 while ($row = $result->fetch_assoc()) {
     // Do something with $row
 }

Suppose a user has a VPN client installed on their machine. The VPN client then creates an encrypted tunnel to the VPN server, and the user can securely send or receive information over the internet.

Following is a list of some most important usage of Hashing:

• Hashing facilitates us to keep and find records of hashed data.
• Hashing can be used in cryptographic applications such as a digital signature.
• With the use of hashing, we can create random strings to avoid data duplication.
• Geometric hashing is a type of hashing used in computer graphics to help find proximity issues in planes.

• Password Length: You can set a minimum length for password. The lengthier the password, the harder it is to find.
• Password Complexity: Including different formats of characters in the password makes brute force attacks harder. Using alpha-numeric passwords along with special characters, and upper and lower case characters increase the password complexity making it difficult to be cracked.
• Limiting Login Attempts: Set a limit on login failures. For example, you can set the limit on login failures as 3. So, when there are 3 consecutive login failures, restrict the user from logging in for some time, or send an Email or OTP to use to log in the next time. Because brute force is an automated process, limiting login attempts will break the brute force process.
