IP spoofing is a technique used to gain unauthorized access to computers, where by the attacker send messages to a computer with a foreign IP address indicating that the message is coming from a trusted host.
Attacker puts an internal, or trusted, IP address as its source. The access control device saw the IP address as it is trusted and then lets it through. IP spoofing occurs when a hacker inside or outside a network impersonates the conversations of a trusted computer. There are two general techniques are used during IP spoofing: A hacker uses an IP address that is within the range of trusted IP addresses.
A hacker uses an authorized external IP address that is trusted. Other uses for IP spoofing: IP spoofing is usually limited to the injection of malicious data or commands into an existing stream of data.
A hacker changes the routing tables to point to the spoofed IP address, then the hacker can receive all the network packets that are addressed to the spoofed address and reply just as any trusted user can.
Why IP Spoofing is easy? A hack bypassing this would be great! Sending a raw email with a telnet-like tool would allow me to spoof any OKIOK addresses from the internal network. However, things are not always so easy, especially when the server is well-configured. After some digging through internal documentation, I discovered that some very specific systems do not have the ability to authenticate through SMTP. The IP addresses of these systems is whitelisted in the configuration on the email server itself.
After more research and some social engineering with our support IT staff, I got an IP address of a whitelisted system from a subnet I can connect to.
Here we go! I connected my computer to the same IP subnet my IP: From this subnet, I am able to communicate with the email server The details of the certificate include the subject domain name, organization, owner of the certificate, the public key of the server, which is essential for validation of the identity of the server, the certificate-issuing authority, issue and expiry date and many such details.
A TLS certificate consists of a public key and a private key that interacts behind the scenes during the transactions. They ensure secure encryption when someone visits a website. After receiving the directions for moving to a secured website, the TLS certificate and public key get shared with the client for secure connectivity and a unique session key.
The browser then confirms the authenticity of the certifying authority and the status of the certificate. The browser sends the symmetric key, and the server decrypts using his private key. This is then acknowledged by the server encrypted with a session key for starting the encrypted session.
Thus this transmission of data with the session key helps in the privacy and integrity of the message. TLS handshakes initiate when a user navigates to an application or website that uses TLS and is a multi-step process. This aids in authenticating the identity of the server, generation of sessions for TLS encryption of messages and establishes a cipher suite for the communication session.
The protocols using handshakes with an asymmetric cipher establish better communication using a symmetric cipher. With this, details of encryption or session keys will be used with the help of public-key cryptography.
After the authentication and encryption of data and signature with the message authentication code, the recipient can authenticate for ensuring the integrity of the data. If any steps fail, then the handshake would fail to result in the connection not being created.
Weaknesses of a TLS Certificate: The greatest loophole existing in the digital era is of the hackers, intruders and cyber scams. TLS Certificate is also affected by them. A few of them are mentioned as under: Poisoning the TLS certificate If the computer gets attacked by malicious software, then the security of the TLS certificate is threatened.
Direct attacks on the Certifying Authority A direct attack on the certifying authority could lead to unauthorized usage of the authorization keys. Certificates issued by error Users allow the certifying authority to authenticate the server for connection purposes.
However, the vulnerability arises when the hackers exploit the certificate. This could lead to misuse of the certificate and compromising the connection issue on the server. Trusting Certificate Authorities: The setup of a CA consists of a Public Key Infrastructure that consists of many components like security infrastructure, auditing systems, practice statements, policy frameworks, all of which are essential for making the certificate secure and reliable.
The model of PKI runs on two systems- root certificates and server certificates. If the root certificate is installed on your device's certificate, it will be easily trusted by the browser. Similarly, every device has a local collection of root certificates from trusted CAs. This aids in protection against misuse of the unintended certificate. Certificate Transparency The CAs post the certificates on the public log servers for validity and to prevent misusage.
For validation, at least one element from the service matches with the elements in the pinset. Several attempts have been made for revising the issues for addressing security concerns for defending the position against potential weaknesses. This aids in several benefits like ease of use, deployment, the flexibility of algorithm, interoperability and many more.

Enterprise risk management is the method of accessing risks to recognize threats to a company's financial health and business opportunities.
An ERM program aims to identify, categorize, and measure an organization's risk tolerance capacity. The standard approach to assessing business risk is to look at financial risks, regulatory risks and operational risks. If the exchange rate falls and interest rates increase, if new products aren't approved by the FDA, or if your main warehouse breaks out with fire. To calculate the probability of an event occurring, multiply the potential impact by the probability of that event occurring.
For low-impact events, even a high probability of occurrence has little impact on the company's overall risk exposure. However, for high-impact events, even a low probability of occurrence may be devastating. Cybersecurity risks are becoming an increasingly important part of the ERM equation, posing a challenge to CISOs and other senior security executives. Quantifying the financial impact of a cybersecurity incident is challenging, if not impossible, and determining the probability of such an event is even more difficult.
The identification of significant risks and the implementation of appropriate risk responses are the cornerstones of ERM. Acceptance or tolerance of risk; avoidance or dismissal of risk; risk transfer or sharing via insurance, a joint venture, or another arrangement; and risk reduction or mitigation via internal control procedures or other risk management activities are all examples of risk responses.
Risk theory or risk policy, risk culture, and risk appetite are all essential ERM concepts. These are manifestations of the organization's risk mentality and the level of risk it is prepared to take.
The following are some examples of commonly used standardsEnterprise Risk Management Advantages Enterprise risk management processCore elements of enterprise risk managementWhat should your enterprise risk management framework include 1. Enterprise Risk Management Advantages : Companies should reflect on the upside of risk as well as the downside when developing ERM initiatives. The conventional strategy focuses on negatives, such as financial losses resulting from currency or interest rate trades in financial markets or financial losses resulting from a supply chain interruption or a cyber assault that threatens a company's information technology.
Companies are also forced to think of competitive opportunities and strategic advantages that can come from risk management that is done well. Some of these "better choices" focus on risk analysis, such as where to place a plant or office abroad. Increased knowledge of the organization's risks and the ability to respond effectively Increased trust in the achievement of strategic goals Compliance with legal, regulatory, and reporting standards has improved.
Efficiencies and productivity of the organization have improved. Enterprise risk management process: Hazard risks are those that pose a significant risk to one's life, health, or property. Risks that are specifically linked to money are referred to as financial risks.
They have financial implications such as cost increases or sales decreases. Strategic risks are those that are influenced or generated as a result of strategic business decisions.
