Question

For this week's blog, you will compose a professional philosophy statement (IT), sometimes referred to as a work statement. This can be a valuable document to include with an application or portfolio, but it is also helpful preparation for interview questions.  This statement will be included as part of your final project/e-portfolio that is due in week four (note the duck icon). Your professional philosophy statement should be 250-500 words.

As you consider what to include in your statement, keep in mind the things that employers find valuable; for example: organization, resourcefulness, work ethic, creativity, motivation, perseverance, adaptability, strong written and verbal communication, and so on. You can address technical skills that you possess, but do not overlook “soft” skills like solid time-management and those listed above.  

Do not simply detail your work experience; that is what your resume is for. Instead, the professional philosophy statement should encapsulate your personal perspective or approach to the work you do (or hope to do once you enter your field). What do you bring to the workplace that is unique and which will help you and your colleagues succeed?

Answer 1

For, the blog I would like to pick up on Cybersecurity as a topic. As we all know that there are many hacks and breaches that are being gone on with the help of the knowledge of penetration testing. I would try to help people who work and also when they are on personal space using the internet. So, here we go.

As the years are passing by, security is growing as one of the most effective fields in the history of computers. There is a need of getting each one of the things secured with the help of internet security with ethical actions. There are many things happening on the web and promising safety without taking any tough measures is one of the impossible tasks nowadays. Hence, companies and individuals have moved to security tools and technologies to keep their information safe while connected to the internet.

Risk Assessment & Threat Vulnerability:

Nowadays, companies have moved on to the Agile or Rapid Application Development SDLC(Software Development Life Cycle) which has been resulting in reducing the development timeframe. Now, starting with the risk assessment, here we go,

1. Collecting Information:
   • The collection of information is one of the major parts that plays in the security of the organization. The URL of the target must be accessible to gain information.
   • Information caught in wrong hands can turn out to be chaos for any organization. Hence, information must always be safeguarded with levels of security.
2. Risk Profiling:
   • Checking the website for each and every type of risks/threats is a very important task and must be carried on with each and every module of the organization's availability in the internet space.
   • There must be things carried out like:
     • Automated threat scanning
     • Penetration Testing
     • Black Box Testing of the source codes
     • Assigning Risk Ratings to the Security Flaws
     • Reporting to higher Authorities
3. Updating Technology:
   • In the current world scenario, it has become very important to update the technologies that are been actively used and must be balanced accordingly.
   • The use of older versions will come with a bunch of vulnerabilities and threats along with the destruction of certain aspects of the organization.
4. Application Fingerprinting:
   • In an organization, there are certain things that must be checked for the known vulnerabilities and exposures. If there, one must always keep it the priority to overcome certain threats in order to run the organization smoothly.
   • The application fingerprinting consists of different levels of assessment. Here are some of the different scopes:
     • Defining Objectives
     • Devising Strategy to overcome threats
     • Role-Based Access Control Matrix
     • Choosing Appropriate Security Tools

Everyone must keep in mind that being safe on the internet is an integral part of the virtual life and must carry on managing the security each time there is any interference of threats or vulnerability. One must also stay updated if using any third-party application as there are many zero-day fixes coming in the applications which help us to stay immune to malware and viruses that have affected the software in the past time.

IT Risk Management:

IT Risk Management is one of the major fields in the information technology and gaining the risk-free software or hardware is the only target at which people look for. Hence, here are some of the key principles in which the human factors work in this field. Here we go,

• The risk assessment is the technique in which the risks are minified using certain techniques. Hence, one of the certain task in it is to identify tasks which are being critical and expose hazards to the information.
• Involving the complete workforce in the identification and conserving the risks through appropriate methods which do not have any effect later on.
• To identify certain human failures which would further make the task tougher and also can lead to an accident with having performance issues at a certain level of use.
• To regularly view the risk of assessing and also making the control measures work completely fine for each and every task.
• The task that has been taken consists of risks, Hence, identifying the human failures in performing the tasks and also making the failures occurs less in the testing phase.
• Controlling the risk from making the whole system failure is also one of the tasks that must be completely focused on as there are certain conditions when people fail in controlling the processes.

Hence, these are the role of the human factors in identifying, controlling and managing the IT Risk Management in order to make the process work without any abruptions.

Firewall:

• A firewall is a software or hardware that has been configured with some protocols for the packets that enter or leave the network. The firewalls are been placed in a network in order to get the network secure.
• With the help of the firewall, the packets get filtered and there is less risk of getting malicious packets through the network which will make the network undergo certain risks.
• They are the software or hardware which can be manipulated by the admin in order to make the network behave as wanted under any circumstances. Hence, they are been installed for increasing the security inside the computer network.

Now, let's talk about how to use the operating system to our advantage in moving one step ahead of the attackers with the help of the security that adds up to the cybersecurity.

Windows/Linux Analysis:

• The question consists of a very broad topic let's narrow the whole process. There are some questions which arose to me after reading the above requirements from which some I have listed below:
  • What is the budget for building such workstation?
  • What tools and techniques are going to be used?
  • How fast is the requirement of the passwords to be cracked?
  • What type of password cracking is going to take place, i.e. brute-force attacks, dictionary attacks,etc.?
  • Which language passwords are being cracked?
• Now let's start with answering each of the above questions. The first question is budget, assuming that this is a big organization the budget would be great to move on with the finest hardware and software configuration.
• Hence, the hardware will be based on the budget which can go from good overclocked processors such as i7 processors or fast servers which can consist of the high-end GPU's or we can use supercomputers with a power plant it all depends on the budget. The faster the better for such a process.
• For, software there is certain software in the market which is recommended as one of the best password cracking software. Some of them are listed below:
  • John- The Ripper
  • Hashcat
  • Hydra
  • Rainbowcrack
  • Aircrack-ng (For Wireless Passwords)
  • Cain & Abel
• The Operating system that I would be recommending here would be Linux as it is faster than other operating systems and also it comes with many of the above-listed software in some of their operating system like Kali Linux, Backtrack5r3, etc.
• It is one of the most used operating systems when it comes to vulnerability and penetration testing and as we know password cracking is a form of penetration testing. Linux can come in handy for such a process.

Hence, these are the requirements for building a digital lab for performing password cracking process in more details.

Hence, these are all the things required.

Actions For Effective Risk Management Capabilities:

The actions that one must take in order to make the risk management effectiveness and up to the mark in management capabilities are as follows:

• Preparing:
  • One must always prepare for the risks and also keep the systems checked for the vulnerabilities.
  • The best approach is to plan and make changes to the system as soon as the updates are launched to a particular system.
  • The planning must work accordingly so that the risks are being minified at the user's end.
• Verifying & Eliciting:
  • Verifying each & every potential risk in the system and if found critical then eliciting the risk will ensure that the risks are eliminated properly.
  • The elimination of the risks is also being done on a certain level so that there are no further risks remaining in the system to check.
• Analyzing gaps & Evaluating:
  • Analyzing for risks is the major activities that must be taken on the developing end because if a risk is analyzed in the earlier stage it is less destructive for the system.
  • Evaluating the level of the risks also become important for the users so as to make the risks less effective on the systems.

Hence, these are actions that could lead to the development of effective risk management capabilities.

Guidelines For Security Policies:

For the security policies, there are certain things to be always taken into consideration, we will discuss all of them as we dive in deep. So here we go,

1. Knowing The Risks:
   • It is the most important part while creating security policies to know what risks are there in the system.
   • How the information is been manipulated at the client as well as the server end. Hence, making the process more secure as data is the part for which security is always compromised.
2. Knowing The Wrongs Done By Others:
   • Knowing that the organizations who have been gone through the certain risks which reside in your system. Learning from the mistakes made by others is always the most effective way of setting guidelines.
   • The guidelines to the security policy consist of the most probable wrong things that each and every organization with similar risks are been doing.
3. Keeping Legal requirements in mind:
   • Many times organizations completely forget about the legal requirements that are been required by the officials.
   • Hence, keeping the legal jurisdictions, data holdings and the location in which you reside is also most important.
   • Recently, this has been the case with Facebook's most controversial data theft.
4. Setting the level of security:
   • The level of the security that is been planned must always be kept in mind with the level of risks that are been residing in the system.
   • Excessive security in the system can also cause hindrance to the smooth business operations and hence, overprotecting oneself can also be a cause to the problem.
5. Training Employees Accordingly:
   • The training of the employees in a certain part of the security is also a major part of the security policy as the employees are the one who makes mistake.
   • So, if one trains their employee in such an order that they minimize the mistakes that are been made it will become great for the system.

Hence, these are the guidelines for creating an effective and functional security policy.

Port Security:

Maintaining the ports according to the needs is one of the most important things which one should consider while listing down the systems to be secure. As it is going to be one of the most important and major parts of port security.

There are certain steps which one should follow for port security which I believe works for every organization:

• Limiting the number of devices on most of the switch ports is to be done in each organization.
• Also using MAC ADDRESSES in the organization must be limited to a certain level of work procedure.

Now, coming to the techniques in securing ports are as follows:

• Making Use of Dynamic MAC Addresses:
  • It becomes important to dynamically configure and also secure the MAC addresses of the devices which are been connected to the certain ports.
  • The addresses must always be stored in the address table so as to keep the data secure and also in working mode.
  • In this technique, we also stay away from forwarding traffic from unspecified devices or devices which are not known to the network.
• Using Static MAC Addresses:
  • It is one of the most useful methods as it secures the MAC addresses by statically configuring each of them with the switch port.
  • The MAC Addresses are also stored in the address table.
  • The static configuration of the network is been stored by default while using port security.
  • The table which stores addresses can be made permanent by actually saving them to the startup configuration.
• Using Sticky MAC Addresses;
  • In this, a technique the MAC addresses are used as hybrid addresses which are being dynamically learned from most of the devices which are being connected with the switch port.
  • The addresses are also being put in the address table and are also been entered into most of the running configuration that is static secure MAC addresses.
  • The MAC addresses are also lost if they are not saved in the startup configurations.

Hence, these are technologies that can be used to reduce port vulnerability.

Cyber Crimes:

When talking about cybercrimes, there are many cyber crimes which are been compromising data across the world of many users. It has been estimated that 37% of total websites are being vulnerable to most basic security vulnerabilities and are been compromised on a daily basis. So, now we are going to talk about cybercrimes. They are as follows:

• Buffer Overflow:
  • The buffer overflow vulnerability is one of the most basic and dangerous vulnerabilities which occurs in the systems due to the insufficient memory management and wrong codes.
  • The main drawback of having this vulnerability is that it will freeze the system and let the attacker do the things he wants to do which can lead to remote code execution and then, later on, can do anything the attacker wishes to.
• SQL Injection:
  • It is wrong references given in the databases and manipulating a certain level of database information which gives access to the attacker in which they can hack the system authentication process.
  • The SQL Injection is one of the most dangerous vulnerability and none of the websites must have this threat in their system because it can cause the downfall of the whole website.

How can encryption be used to ensure the integrity and maintain data privacy?

• Encryption is one of the best techniques which can be used by a user so that the data gets encrypted and decrypting is not the thing which is easy and also with certain attacks it could take a lot of time to even decrypt single encryption.
• It will help in managing the integrity of the data by keeping the data consistent with the help of the encryption that takes place in the systems. It takes a lot of time and brain to break the code which most of the attackers don't like doing unless and until it is juicy enough to get them millions of bucks.

The basic encryption algorithm and how it works.

• The most basic encryption algorithm that is been used is AES(Advanced Encryption Standard). It is one of the most standard algorithms which is been trusted a lot and follows the standards that are been set by the American Standards.
• The main advantage of the algorithm is that it uses very less RAM and works very efficiently. It can be used for many variants which include 128,192,256 bits.
• In AES, there are basically 10 rounds which are been used for 128-bit keys. The same key is used for encryption as well as decryption of the data. According to the data, until now there are no attacks which are been discovered to be effective in AES.
• Hence, it remains the safest algorithm for encryption and is been used on certain devices and transmission technologies. It is mostly used for wireless connections authentication.
• While going on with the encryption one must always be sure about what is being used and what is to be encrypted. The user base is going to handle the data.
• The more important the data, more security for the data. This means that the algorithm like Triple DES etc. must be used if data is too confidential and can harm a lot of people if leaked.
• There are also certain factors to which the system relies on. Hence, the algorithm must be full proof of attacks and the security must be to the ultimate level.

Security Implementation:

• The system must implement a firewall with honeypots for advanced security. In the firewall, there must be both the hardware and software version installed as both the version have some disadvantages over each other.
• Hence, it will nullify each of the disadvantages and can be used for different calibers in the system. As the software firewall can be used for adding rules and all the administrator stuff.
• And, the hardware firewall can be used to gain security for the packets that are entering the network and exiting the network. The honeypots will come in action before the firewall.
• What honeypots actually do in such conditions, the honeypots acts as a real system faking the attacker as, if, his attack has been a success. Honeypots can be considered as a mirage to our actual system.
• Hence, the attacks information can be later on used for upgrading the actual system and securing it from the discovered vulnerabilities or loopholes.

Hence, this is what one must do for ensuring the illegal activities in the system.

Example Threat:

I have an example for the real-life technological security flaw which has been appeared in one of the most used applications,i.e. Adobe Flash Player. So here is the information related to it in detail:

• The vulnerability which we are going to talk today is one of the most critical ones and for one of the largest companies "Adobe". This vulnerability left lakhs of the user under danger of getting breached.
• The name of the vulnerability is "Flash Player Vulnerability" with an identification code "CVE-2018-5002". This vulnerability has been affecting densely in the Middle East region and was brought into vision in June 2018.
• What actually was the security flaw here? The security flaw was one of the stack-based buffer overflow bugs that have been able to execute arbitrary code.
• The following vulnerability was allowing the attackers to maliciously craft the Flash object which would help them in executing codes in the victim machine and then execute the range of payloads & actions.

How would have this been prevented?

• The applications are been vulnerable to buffer overflow bugs when there are certain programming errors or memory leaks left in the programming.
• Hence, this can be prevented using right programming methods and also putting best programming techniques to use so that none of the vulnerabilities are left in open to ruin the applications.
• There must be thorough testing of the application done before releasing the application publicly and must also make the application good enough for working against the vulnerabilities.

Hence, these are the methods in which the vulnerability could have been prevented.

How did this vulnerability actually work?

• The vulnerability was allowing the attacker to provide a word file to download and once executed in the victim PC the adobe flash exploits would start running.
• This file once executed starts executing the shellcode which will then enable the attacker to command and control the servers from which the attacker would gain complete access to the victim machine.

Patch For Vulnerability:

• The company has declared the patch for the vulnerability and can be patched automatically by installing the updated Flash Player as this was a critical zero-day attack.
• The patch is available only for the users from East Asia as the vulnerability was highly active in that region.

Hence, this was all on technology security and how to maintain the security levels in order to stay updated and up to the mark in this world to stay alert and away from the attackers.
