Data loss has become one of the biggest risk factors of inter-connectedness. The internet has made our lives convenient, but it has exposed businesses and individuals to malicious threats that can wreak havoc with a few lines of code.

Cybersecurity is paramount for businesses. If they do not protect customer data, they are liable for its loss. The average small business spends tens of thousands of dollars to ensure that customer data is protected.

Unfortunately, cybersecurity is one of those terms that is much used but little understood. It is often confused with IT security, which is an umbrella term for security for all things electronic.

What is cybersecurity?

Cybersecurity is the protection and security of connected devices. If a device is connected to another device, whether internally or externally, there is potential for harm. Cybersecurity attempts to eliminate risk using a variety of techniques to secure devices and networks.

Because of the number and frequency of attacks in recent years, cybersecurity professionals are highly valued. Businesses and other organizations are willing to pay six-figure incomes to individuals who have the skills to keep their networks and data secure.

You can become an expert by enrolling in an online computer science masters degree at Baylor University. You don’t need to have a background in computer science or IT to join a class. So long as you have a bachelor’s in a related field, you are eligible to enroll in the program.

The program takes about 15 weeks, and all classes are online. You will cover topics like databases, software engineering, data communications and management, operating systems and cybersecurity.

When learning about cybersecurity, you will discuss core concepts such as cryptography, cybersecurity tools, malware and reverse engineering. You will also be introduced to reverse programming and instruction detection and prevention.

What are the different types of cybersecurity?

Cybersecurity is a broad field that can be summed up in seven main elements:

  • Network security

This is the most common type of cybersecurity. It identifies and stops attacks that are designed to infiltrate networks from both inside and outside the organization.

It uses a variety of methods to protect networks while allowing authorized user access. One of the most common is a firewall, which works as a buffer between the network and untrusted connections that may introduce malicious bugs into the system.

Network security is key to keeping emails secure. It scans incoming emails to eliminate threats like phishing attacks.

  • Cloud security

This type of security has become vital as more and more businesses adopt cloud storage. Experts are in charge of developing strategies and protocols that govern how data is uploaded, accessed and protected.

These experts ensure that everyone in the organization has the right tools to access information when they need it, and they design software to prevent unauthorized access.

Cloud security experts are also tasked with identifying the best cloud solutions for organizations. They weigh different options to find out which one best aligns with the business’ goals.

  • Application security

Businesses have become heavily reliant on apps, which have introduced convenience to everyday operations for both customers and employees. Application security is the process of securing all apps that are used within the business.

It uses features like two-step authentication and biometric identification. It also ensures that all data collected through apps is securely uploaded to databases and the cloud.

  • Endpoint security

This is about securing end-user devices like PCs, laptops and mobile phones. It uses anti-phishing software, antivirus software and anti-ransom software. It also detects and eliminates threats using forensic techniques such as end-point detection and response.

  • Mobile security

A lot of corporate and business data is handled using mobile devices. A good cybersecurity strategy defines how such devices should be protected. It ensures that only secure and authorized devices are allowed to access the system.

Mobile security prevents attacks on mobiles, laptops and tablets using modern device management solutions.

  • Internet security

Also called IoT (internet of things) security, it aims to protect devices that are connected to the internet. Hackers and other malicious actors seek out vulnerable devices and plant code to infiltrate systems and gather information.

The job of an internet security expert is to develop and deploy protocols to protect these devices and eliminate threats as soon as they are detected.

Common cybersecurity threats

The above methods are deployed to fight a variety of threats, including:

  • Malware – This is software designed to cause damage. The most common malware is a computer virus.
  • Ransomware – This is a new type of threat, but it has caught on fast. Hackers get hold of sensitive data or lock down systems and demand a ransom before they will restore normal operations.
  • Phishing attacks – These usually infiltrate through email and are designed to steal sensitive user information.
  • Social engineering – This involves manipulating people to divulge sensitive information.

What jobs are available for cybersecurity experts?

There are numerous job opportunities available to those who complete an online computer science master’s. You can become a cybersecurity engineer or a cybersecurity analyst. Some people opt to become network analysts or engineers and oversee network security.

The master’s qualifies you to work in vulnerability analysis. You can also be employed as a cybersecurity consultant or engineer to help design and implement security protocols for businesses.

If you would like to advance your career further, it is important to have your ear on the ground as far as cybersecurity is concerned. You should attend courses and seminars to learn about the latest threats and the best way to combat them.

If you are exceptional at what you do, you will eventually work in senior management as a director of cybersecurity.

Conclusion

Malicious cyber threats are an everyday phenomenon. Hackers have proved to be wily, finding ways to bypass security systems all the time. To prevent the loss of sensitive customer data, companies are willing to pay top dollar to professionals who can guarantee system safety.

An online computer science master’s has the potential to take you to the top of the cybersecurity profession. It doesn’t take a long time to complete, and you don’t need to have a background in computer systems to enroll in a degree program.

Portrait Photography Techniques: Creating Expressive Images

Published

on

portrait-photography-techniques-creating-expressive-images

Creating expressive portraits requires not only the ability to handle the camera but also an understanding of psychology and working with the model. Portrait is the art of capturing not only a person’s appearance but also their emotions, character, and personality. 

Importance of light

Light is very important for creating the atmosphere and therefore the expressiveness of a portrait in several aspects at once.

  • Light determines the shape, texture, and volume of an object, in this case, the model’s face.
  • The right lighting will help to emphasize the best features of the face and hide flaws. If the camera still “noticed” some defects, you can remove them in the process of retouching. For example, if you want to get a smooth skin app Retouchme will fix the photo in a couple of clicks.
  • Lighting effects and shadows can be used to create emotionally rich portraits. Soft lighting can create a gentle and romantic mood, while harsh shadows add drama and intrigue.

If you choose to shoot in natural light, avoid high sun: it gives harsh shadows. The optimal time to work is the photographer’s golden hour. If the day is cloudy, the light will be soft and diffused, so you can shoot even at noon.

Studio portrait photography uses softboxes, light panels, and reflectors to control the direction and intensity of the flow. Professional lighting is usually more predictable and controllable, so the photographer will be able to create the effects they want and adjust their work on the fly.

Flashes when shooting a model help create bright contrasting portraits and are also used to soften shadows when working with natural light.

Composition and angle

For a model to “read” well in the frame, you need to think about the position of the face and the direction of the lens. What basic techniques does the photographer rely on?

1. Rule of thirds.

Divide the frame into nine equal parts. Position the main subject (in this case, the model’s face) near the intersection of the lines.

2. Diagonal lines.

Use diagonal lines in your composition to direct the viewer’s eye toward the face. Position the model so that the eye line tends to run along the diagonal line.

3. Positioning the main object.

Place the main subject (the face) in the center of the frame – this is how you get a confident and focused image. Use the golden ratio by positioning the model on one of the lines to achieve a balance between the main object and the space around it.

4. Use of negative space.

Leave enough space around the model’s face to create a sense of “breathing” and depth.

5. Work with foreshortening.

Experiment with shooting directions, such as a high or low angle.

6. Use background.

Include prominent details such as trees or architecture to create an interesting background. Use surrounding elements as a frame for the model’s face to draw attention to the main subject of the portrait.

These tips will help you shoot expressive portraits just by working with composition alone.

Creative angles: unconventional approaches to portraiture

Experiment with blurred backgrounds or using macro photography to create unconventional effects in portraits. This can help highlight the main subject and add dynamics to the image.

  • Use mirrored or reflective surfaces (glass, water, metal) to create unique effects in portraits. 
  • Try using the model’s movement while shooting by setting a slow shutter speed.
  • Use aerial platforms, drones or other devices to get unconventional angles from above or below. 

Is the background important for an expressive image?

The choice of surroundings plays a key role in creating the overall image that the viewer will see. Here are a few techniques that will add just the right amount of expression to your images.

  • Try to achieve contrast between the background and the model’s face or, conversely, create harmony by using complementary colors and textures.
  • Take into account the style and character of the portrait. For example, use natural surroundings if you want to achieve a calm image, or add abstract details for a non-basic role.
  • Match the background to the mood you want to convey, such as light and bright colors for a joyful and optimistic portrait or darker tones for a mysterious and dramatic mood.
  • A minimalistic background, such as a solid-colored wall, will focus the viewer’s attention on the model’s face. A rich environment with interesting objects and textures will set the mood before the camera is even turned on.

As you can see, the right choice of frame filling will enhance the expressiveness of the portrait and emphasize its character.

Shooting portraits is not just a process of creating images, it is an opportunity to see the moments of life, to express the individuality and uniqueness of each person. With the right techniques, the photographer captures images that will inspire.
