Data breach in 2022: Introduction to incident management in cybersecurity

To put it simply, a data breach refers to any incident involving the theft of information from a system without the knowledge or authorization of the system’s owner. In recent years, cybersecurity breaches have multiplied like never before! Be it large or small companies, there’s hardly any sector that is not vulnerable to cybercrime. 

The latest incidents of high-profile attacks targeting a wide spectrum of sectors, including healthcare, finance, retail, government, manufacturing, and energy, have compelled industry insiders to sit up and take notice of the threat landscape. Going by expert projections, cybercrime is expected to cost the global economy $10.5 trillion by 2025, alarming to even mammoth businesses.

best cybersecurity courseIncident management in cybersecurity implies the process of identifying, managing, recording, and analyzing the security, threats, and incidents associated with cybersecurity.

It is a crucial step that immediately follows or precedes a cyber disaster in an IT infrastructure. Incident management in cybersecurity requires a significant degree of knowledge and experience. 

With efficient incident management in place, you can considerably minimize the adverse impact of cyber destruction, besides keeping cyber-attacks at bay.

What’s more, it also prevents data leaks. An organization without a good incident response plan might fall prey to cyberattacks, which can lead to major compromises with the data of the organization.

The following steps are involved in incident management in cybersecurity:

  1.     The first step involves an alert that reports an incident that has occurred. This is followed by the engagement of the incident response team, which prepares itself to tackle the incident.
  2.     Next comes identifying potential security incidents by monitoring and reporting all incidents.
  3.     Based on the outcome of the previous step, the next step is responding to the incident by containing, investigating, and resolving it.
  4. Finally, every incident should be documented with its learnings and key takeaways.

Also, check out the following tips for security incident management:

  1.  It is imperative for every organization to ensure a mature and fool-proof incident management process that implements the best practices for a comprehensive plan.
  2.   Make sure your incident management plan is equipped with supporting policies that include well-laid-out guidance on the detection, reporting, assessment, and response of the incidents. A checklist should be prepared, putting down the actions based on the threat. The incident management plan should also be continuously updated as per requirement, especially with regard to lessons learned from previous incidents.
  3.  Creating an Incident Response Team (IRT) plays an instrumental role in working on clearly defined goals and responsibilities. It will also be entrusted with functional roles such as finance, legal, communication, and operations.
  4.  Incident management procedures can go quite a few notches higher with regular information security training and mock drills. These go a long way in boosting the IRT’s functionality and keeping them on their toes.
  5.   A post-incident analysis after any security incident can make a considerable difference in teaching you a thing or two about successes and failures. This helps a lot in making necessary adjustments to the program and incident management processes as and when required.

What More You Need

In incident management in cybersecurity, collecting evidence and analyzing forensics is always highly recommended, which is an integral part of incident response. You need the following things for the same:

  • A well-defined policy can effectively assimilate evidence while ensuring its accuracy and sufficiency to be admissible in a court of law.
  • The incident response should be such that it can employ forensics as required for analysis, reporting, and investigation.
  • The IRT personnel must be well-trained in cyber forensics and functional techniques. They should also have some knowledge of legal and governance issues. You can visit our training centers in Mumbai, Thane, Pune, Chennai, Bengaluru, Delhi, and Gurgaon for cybersecurity training online. 

In a nutshell, a robust incident management process can reduce your recovery costs and potential liabilities and, above all, minimize the damage to the victim, not only at a personal level but also at the organizational level.

Learn Computer Vision: What is Hyberbolic Image Segmentation?

Currently, we carry out optimization at the pixel level in Euclidean embedding spaces for segmenting images. We do this through linear hyperplanes (2D visualization). Keep reading to clear your concept for the Artificial Intelligence Course regarding a key alternative for image segmentation that is done in hyperbolic space. 

Computer Vision is one of the most exciting topics covered in Artificial Intelligence and Machine Learning Certification. This field allows systems and computers to retrieve important information from digital visuals like images and videos. Based on the received data, computers process information to make suggestions to the user. 

If we were to simplify the concept, computer vision tries to make computers view images and videos the way humans do. Today, the advancement in deep learning and neural networks has made these systems exceed human performances in some aspects like object detection. 

Today, spherical and Euclidean embeddings dominate the most-used tasks of computer vision like image retrieval and image classification. 

On the other hand, Hyperbolic Image Segmentation is one of the latest standards for segmenting images. It offers multiple practical benefits like: 

  • Uncertainty estimation
  • Boundary information
  • Zero-label generalization 
  • Increased performance in embeddings of low-dimension

Why do we use Hyperbolic Image Embeddings? 

In Natural Language Processing (NLP) tasks, hierarchies are ubiquitous. The widespread presence of these tasks motivates the use of hyperbolic spaces in this field. This is because hyperbolic spaces inherently embed tree graphs and other types of hierarchies with minimum distortion. 

While retrieving an image, you will notice that an overview picture of something can be mapped to the closeups of many unrelated pictures. These pictures might have a wide range of dissimilarities in their details. 

Furthermore, let’s consider classification tasks. For such tasks, an image that contains representations from many classes is generally connected to images that possess the representatives of those classes in insulation. Thus, the process of embedding such a dataset, which contains composite images, into a continuous space is said to be similar to hierarchy embedding. 

There are also some tasks where generic images are used. These images could be related to obscure images because they lack much information. For example, if face recognition software is run over an image that contains a blurry face, the software could match the unclear image with the high-resolution images of many different people. 

There are several inherent hierarchies in NLP that go beyond to reach the visual region. For instance, you can use hierarchical grouping to visually represent different species of plants. 

Collectively, using hierarchical relations in AI increases the demand for hyperbolic spaces for output embedding. As the volume of Euclidean spaces expands, the resulting expansion is polynomial in nature. However, the expansion of hyperbolic spaces is exponential. This results in the generation of continuous tree analogues. 

This information makes it possible to conclude that the unrevealed hierarchy of visual information can be captured by the expanding hyperbolic output embedding.

5 steps to implement agile hiring

What is agile hiring?

Agile is a concept borrowed from software development. Agile relies on the constant interchange of feedback between the stakeholders of the project. The feedback is used to identify shortcomings in the processes and eliminate them to obtain better outcomes.

best Agile hiringAnalogously, agile hiring is aimed at being more cognizant of the needs of the organization and making the process more efficient. 

Agile hiring achieves this through continuous feedback and process improvement. Agile hiring is adopted to address talent shortages, reduce the length of the hiring processes, and enhance collaboration. 

The agile hiring approach uses a framework of checkpoints and ‘sprints’ to ensure that the process remains on track. 

What are the benefits of agile hiring?

Agile hiring enhances the efficiency of the hiring process, improves the quality of the hire, and also improves the candidate experience. The other benefits that accrue from agile hiring include:

  • The process of continuous feedback, analysis, and decision-making based on data enables the refinement of the hiring process.
  • It aids in lowering the cost per hire by enabling the efficient utilization of resources.
  • Agile hiring affords the recruiters greater flexibility in being able to pivot promptly between possible tactics and strategies. 
  • It brings about greater focus among the members of the team by directing their attention to actions that aid the attainment of the targeted outcome.
  • The culture of feedback inherent in agile hiring fosters an attitude of collaboration and open communication.

A Gartner study found that agile hiring reduces the cost per hire by 37%, reduces time to fill roles by 22%, and increases recruiter productivity by 31%.

The 5 steps in agile hiring

As discussed, agile hiring is an iterative process. The steps that make up agile hiring include:

  1. Defining the job requirement. This is probably the most important step in the agile hiring process. The concerned stakeholders (hiring manager, recruitment manager, etc.), after the need for hiring has been established, should outline, precisely, the requirements of the position and define the expectations from the position. 
  2. Put the team together. Once the attributes of the person to be hired have been established, the next step involves putting together a team to undertake the hiring. Within this team, responsibilities should be clearly delineated and the details of the process and the targeted outcomes disseminated to all the members of the team. This will ensure a common understanding of the task and obviate any possibility of confusion during the periodic feedback and review meetings. 
  3. Attract candidates. This activity encompasses several tasks – such as defining the job description, releasing the hiring ads, and identifying and contacting passive candidates. As each task is completed, collect feedback, review progress, and assess the quality of the applicants. If the applicant quality does not meet targeted requirements, the outreach strategy should be suitably modified. 
  4. Candidate screening and interviewing. In this step, received applications are shortlisted, and preliminary interviews are scheduled with the shortlisted candidates. If the pool of candidates does not meet expectations, this is another opportunity to change the messaging and candidate sourcing channels. 
  5. Candidate selection/rejection. At this stage of the hiring process, shortlisted candidates fitting the job criteria are interviewed to select the best person for the position. Like every step, this step is also used to review the sourcing and screening process. If at the end of this step a final offer letter is issued, it signals the end of the hiring. If not, then steps 3,4,5 are repeated and the process refined further to attain the desired outcome.

Final Thoughts

In agile hiring, final candidate selection does not signal the end of the process. The process is closed only after the candidate’s performance has been evaluated after a reasonable amount of time and his/her fit into the organization has been assessed. The purpose of this assessment is to assess the efficacy of the hiring process and identify areas for improvement.
