It originates from a military strategy by the same name, which seeks to delay the advance of an attack, rather than defeating it with one strong line of defense. Defense-in-depth cybersecurity use cases include end-user security, product design and network security.

Defense in Depth (DiD) refers to an information security approach in which a series of security mechanisms and controls are thoughtfully layered throughout a computer network to protect the confidentiality, integrity, and availability of the network and the data within.

Defense in Depth (DiD) is an approach to cybersecurity in which a series of defensive mechanisms are layered in order to protect valuable data and information. Unfortunately, there is no single method that can successfully protect against every single type of attack. …

Defense in depth can be divided into three areas: Physical, Technical, and Administrative.

The Principles of Security can be classified as follows:

• Confidentiality: The degree of confidentiality determines the secrecy of the information.
• Authentication: Authentication is the mechanism to identify the user or system or the entity.
• Integrity:
• Non-Repudiation:
• Access control:
• Availability:

Types of Physical Barriers:

• Chain Link Fences. Chain link fences are an effective and affordable option that can wrap around the border of your property and protect the area from human or animal intrusions.
• Ornamental Fences.
• Razor Wire/Barbed Wire.
• Bollards.
• Barrier Gates.
• Security Glass.
• Bars on Windows.
• Access Control System.

Physical security is the part of security concerned with physical measures designed to protect the assets and facilities of the organization. The three parts to physical security standards for various types of army equipment and the risk level is access control, surveillance, and security testing.

There are three primary areas or classifications of security controls. These include management security, operational security, and physical security controls.

5 physical security tips for protecting your digital devices

1. Password-protect your computing devices.
2. Always backup your files.
3. Use tracking software to help get your stolen device back.
4. Don’t tempt thieves with unattended mobile devices, particularly in public places.
5. Encrypt sensitive data.
6. Bonus tip.

Businesses are constantly at risk of theft, particularly when their physical assets aren’t fully secure. The best way to keep thieves at bay is to break down security into four layers: deterrence, access control, detection and identification.

Defense in depth (also known as deep or elastic defense) is a military strategy. It is a delaying tactic intended to slow down the advance of an enemy instead of stopping them. The tactic buys time by yielding to the enemy slowly. It usually causes additional casualties.

Defense-in-depth is a security risk management approach that defines multiple layers of security controls in an IT environment so that if a security attack is not caught by one layer, it will probably be caught by next. …

A network security group (NSG) contains a list of security rules that allow or deny network traffic to resources connected to Azure Virtual Networks (VNet). NSGs can be associated to subnets or individual network interfaces (NIC) attached to VMs.

Azure Firewall is a managed, cloud-based network security service that protects your Azure Virtual Network resources. Azure Firewall uses a static public IP address for your virtual network resources allowing outside firewalls to identify traffic originating from your virtual network.

In conclusion, Azure Sentinel is a powerful SIEM fit for the modern technological landscape. It provides a bird’s-eye view of your entire IT estate along with smart analytics supported by advanced artificial intelligence to help detect and respond to threats in near real-time.

Azure Sentinel provides a threat detection and mitigation service that helps you to detect incidents and threats when they happen and helps you to solve them as effectively as possible. In this post, we’ll explore what Azure Sentinel is and how you can use it to protect your organization.

Azure Sentinel is a cloud-native security information and event manager (SIEM) platform that uses built-in AI to help analyze large volumes of data across an enterprise—fast.

Azure Sentinel, in addition to being a Security Information and Event Management (SIEM) system, is also a platform for Security Orchestration, Automation, and Response (SOAR).

Microsoft 365 E5 and Microsoft 365 E5 Security customers can get Azure credits towards up to 100MB per user/month of Microsoft 365 data ingestion into Azure Sentinel.

The Sentinel-1 Toolbox (S1TBX) consists of a collection of processing tools, data product readers and writers and a display and analysis application to support the large archive of data from ESA SAR missions including Sentinel-1, ERS-1 & 2 and ENVISAT, as well as third party SAR data from ALOS PALSAR, TerraSAR-X, COSMO …

The main objective of the Sentinel-3 mission is to measure sea surface topography, sea and land surface temperature, and ocean and land surface colour with high accuracy and reliability to support ocean forecasting systems, environmental monitoring and climate monitoring.

Microsoft Azure Sentinel is a scalable, cloud-native, security information event management (SIEM) and security orchestration automated response (SOAR) solution.

Free Trial Azure Sentinel can be enabled at no additional cost on an Azure Monitor Log Analytics workspace for the first 31-days. Charges related to Azure Monitor Log Analytics for data ingestion and additional capabilities for automation and bring your own machine learning are still applicable during the free trial.

Pay-as-you-go

Feature	Price
Azure Sentinel	$3.38 per GB ingested

Sentinel customers will need to provide for Log Analytics costs. Pay-As-You-Go pricing for Azure Log Analytics is $2.76 per GB, including 5-GB per customer per month free, making some Sentinel-analyzed data cost up to $5.15 per GB at combined Pay-As-You-Go rates.

By expanding on cloud-scale data collection, and on Microsoft’s own risk detection tools, Azure Sentinel can automate reaction using coordination over your whole domain. It’s Software as a service (SaaS) so it’s versatile, and you just pay only for the resources you use.
