What does a security audit system do?

1.What is the role of the security audit system?

The tracking function of security audit is to help security personnel to audit the reliability and security of the system, report the obvious attempt to hinder the operation of the system to the security console in time, and take timely measures. Generally, a security and confidentiality detection and control center should be established in the network system, which is responsible for monitoring, controlling, processing and auditing the security of the system. All security and confidentiality service functions, smart contract audit services all layers in the network are related to the audit trail system.

2. What aspects does the security audit system include?

A security audit involves four basic elements: control objectives, security vulnerabilities, control measures, and control tests. Among them, the control target refers to the security control requirements formulated by the enterprise according to the specific computer application and the actual situation of the unit. A security vulnerability refers to a weak link in a system’s security that can easily be interfered with or destroyed. Control measures refer to the security control technologies, configuration methods and various normative systems formulated by enterprises to achieve their security control objectives. Control testing is to compare the consistency of various security control measures of the enterprise with the predetermined security standards, to determine whether various control measures exist, smart contract audit whether they are implemented, whether the prevention of vulnerabilities is effective, and to evaluate the reliability of enterprise security measures. Obviously, as a special audit project, security audit requires auditors to have strong professional technical knowledge and skills.

3. What are the aspects of network security?

1. System security: the security of information processing and transmission systems. It focuses on keeping the system up and running. Avoid damage and loss of messages stored, processed and transmitted by the system due to system breakdown and damage.

2. Network information security: the security of system information on the network. Including user password authentication, user access authority control, data access authority, mode control, security audit, security problem follow-up, computer virus prevention, data encryption, etc.

3. Information dissemination security: Information dissemination security on the network includes information filtering. It focuses on preventing and controlling the consequences of the dissemination of harmful information, avoiding the runaway of information freely transmitted by the cloud on public networks.

4. Information content security: the security of information content on the network. It focuses on protecting the confidentiality, authenticity and integrity of information. Avoid attackers taking advantage of the security leaks of the system to conduct, bsc smart contract audit impersonate, defraud and other behaviors that are detrimental to legitimate users.

What does a security audit system do? What aspects does a security audit system include? At present, there are many security audit systems on the market, and many companies have begun to develop them independently. You can take a look at the performance of the products and compare them comprehensively.

Everything around us has become smart, like smart infrastructures, smart cities, autonomous vehicles, to name a few. The innovation of smart devices makes it possible to achieve these heights in science and technology. But, data is vulnerable, there is a risk of attack by cybercriminals. To get started, let’s know about IoT devices.

What are IoT devices?

The Internet Of Things(IoT) is a system that interrelates computer devices like sensors, software, and actuators, digital machines, etc. They are linked together with particular objects that work through the internet and transfer data over devices without humans interference.

Famous examples are Amazon Alexa, Apple SIRI, Interconnected baby monitors, video doorbells, and smart thermostats.

How could your IoT devices be vulnerable?

When technologies grow and evolve, risks are also on the high stakes. Ransomware attacks are on the continuous increase; securing data has become the top priority.

When you think your smart home won’t fudge a thing against cybercriminals, you should also know that they are vulnerable. When cybercriminals access our smart voice speakers like Amazon Alexa or Apple Siri, it becomes easy for them to steal your data.

Cybersecurity report 2020 says popular hacking forums expose 770 million email addresses and 21 million unique passwords, 620 million accounts have been compromised from 16 hacked websites.

The attacks are likely to increase every year. To help you secure your data of IoT devices, here are some best tips you can implement.

Tips to secure your IoT devices

1. Change Default Router Name

Your router has the default name of make and model. When we stick with the manufacturer name, attackers can quickly identify our make and model. So give the router name different from your addresses, without giving away personal information.

2. Know your connected network and connected devices

If your devices are connected to the internet, these connections are vulnerable to cyber attacks when your devices don’t have the proper security. Almost every web interface is equipped with multiple devices, so it’s hard to track the device. But, it’s crucial to stay aware of them.

3. Change default usernames and passwords

When we use the default usernames and passwords, it is attackable. Because the cybercriminals possibly know the default passwords come with IoT devices. So use strong passwords to access our IoT devices.

4. Manage strong, Unique passwords for your IoT devices and accounts

Use strong or unique passwords that are easily assumed, such as ‘123456’ or ‘password1234’ to protect your accounts. Give strong and complex passwords formed by combinations of alphabets, numeric, and not easily bypassed symbols.

Also, change passwords for multiple accounts and change them regularly to avoid attacks. We can also set several attempts to wrong passwords to set locking the account to safeguard from the hackers.

5. Do not use Public WI-FI Networks

Are you try to keep an eye on your IoT devices through your mobile devices in different locations. I recommend you not to use the public WI-FI network to access them. Because they are easily accessible through for everyone, you are still in a hurry to access, use VPN that gives them protection against cyber-attacks, giving them privacy and security features, for example, using Express VPN.

6. Establish firewalls to discover the vulnerabilities

There are software and firewalls like intrusion detection system/intrusion prevention system in the market. This will be useful to screen and analyze the wire traffic of a network. You can identify the security weakness by the firewall scanners within the network structure. Use these firewalls to get rid of unwanted security issues and vulnerabilities.

7. Reconfigure your device settings

Every smart device comes with the insecure default settings, and sometimes we are not able to change these default settings configurations. These conditions need to be assessed and need to reconfigure the default settings.

8. Authenticate the IoT applications

Nowadays, every smart app offers authentication to secure the accounts. There are many types of authentication methods like single-factor authentication, two-step authentication, and multi-factor authentication. Use any one of these to send a one time password (OTP) to verify the user who logs in the smart device to keep our accounts from falling into the wrong hands.

9. Update the device software up to date

Every smart device manufacturer releases updates to fix bugs in their software. These security patches help us to improve our protection of the device. Also, update the software on the smartphone, which we are used to monitoring the IoT devices to avoid vulnerabilities.

10. Track the smartphones and keep them safe

When we connect the smart home to the smartphone and control them via smartphone, you need to keep them safe. If you miss the phone almost, every personal information is at risk to the cybercriminals. But sometimes it happens by accident, makes sure that you can clear all the data remotely.

However, securing smart devices is essential in the world of data. There are still cybercriminals bypassing the securities. So make sure to do the safety measures to avoid our accounts falling out into the wrong hands. I hope these steps will help you all to secure your IoT devices.

If you have any, feel free to share them in the comments! I’d love to know them.

Lax Security Exposes Smart-Irrigation Systems to Attack Across the Globe

More than 100 smart-irrigation systems deployed across the globe were installed without changing the factory’s default, passwordless setting, leaving them vulnerable to malicious attacks, according to recent findings from Israeli security research firm Security Joes.

The researchers immediately alerted CERT Israel, the affected companies and the irrigation system vendor, Mottech Water Management, which did not immediately respond to a request for comment from Threatpost.

Mottech’s system allows for real-time control and monitoring of irrigation for both agricultural and turf/landscaping installations, via desktop and mobile phone. Sensor networks allow for the flexible and real-time allocation of water and fertilizer to different valves in the system. Access to the network could result in an attacker being able to flood fields or over-deliver fertilizer, for instance.

Security Joes regularly scans for Israeli open devices on the internet to check for vulnerabilities, the firm’s co-founder Ido Naor told Threatpost. Recently, its researchers discovered that 55 irrigation systems within Israel were visible on the open internet without password protections. After expanding their search, they found 50 others scattered around the world in countries including France, South Korea, Switzerland and the U.S.

“We’re talking about full-fledged irrigation systems, they could be entire cities,” Naor said. “We don’t look closely at what’s behind the address, because we don’t want to cause any trouble.”

Naor said that at last check, only about 20 percent of the identified vulnerable irrigation devices have had mitigation efforts taken to protect them so far.

Israel’s Water Systems Under Attack

There’s good reason for alarm about water systems not being secured, particularly in Israel. Just last April, a cyberattack on Israeli water systems, reportedly launched by Iran, attempted to increase the mix of chlorine in the water to poison the civilian population and ultimately interrupt the population’s water supply, The Times of Israel reported.

Yigal Unna, the head of the country’s National Cyber Directorate addressed the CybertechLive Asia conference in late May with the ominous warning that the direct cyberattack on people represented a new chapter in cyberwarfare, according to The Times of Israel.

“Cyber-winter is coming and coming even faster than I suspected,” he told the conference, according to the report. “We are just seeing the beginning.”

Unna was correct. Just weeks later in July, the Israeli Water Authority said that it was able to stop an attack on agricultural water pumps in Galilee, and another on water-supply infrastructure in the “center of the country,” reports.

The irrigation systems which were discovered without password protection aren’t related to the previous attacks, Naor said.

Locking Down Utilities Beyond Israel

These types of vulnerabilities certainly aren’t limited to Israel.

Last month, six critical flaws in CodeMeter, software used to power industrial systems in the U.S., including water and electric utilities, were discovered which could be exploited to launch attacks or even allow third-party takeovers of systems.

Over the summer, researchers found that VPNs used for remote access to operational technology (OT) networks in industrial environments left field devices open to attacks, which could cause shutdowns or even physical damage.

Governments are making attempts to keep up with the proliferation of internet-of-things (IoT) devices throughout critical-infrastructure systems. In the U.S., the House of Representatives passed legislation in September establishing minimum requirements for IoT devices within the federal government.

“Most experts expect tens of billions of devices operating on our networks within the next several years as the [IoT] landscape continues to expand,” the legislation’s so-sponsor Senator Cory Gardner (R-Co.) said in a press release. “We need to make sure these devices are secure from malicious cyberattacks as they continue to transform our society and add countless new entry points into our networks, particularly when they are integrated into the federal government’s networks.”

System Databases in SQL Server

Introduction

In SSMS, we many of may noticed System Databases under the Database Folder. But how many of us knows its purpose?. In this article lets discuss about the System Databases in SQL Server.

System Database

Fig. 1 System Databases

There are five system databases, these databases are created while installing SQL Server.

  • Master
  • Model
  • MSDB
  • Tempdb
  • Resource
Master
  • This database contains all the System level Information in SQL Server. The Information in form of Meta data.
  • Because of this master database, we are able to access the SQL Server (On premise SQL Server)
Model
  • This database is used as a template for new databases.
  • Whenever a new database is created, initially a copy of model database is what created as new database.
MSDB
  • This database is where a service called SQL Server Agent stores its data.
  • SQL server Agent is in charge of automation, which includes entities such as jobs, schedules, and alerts.
TempDB
  • The Tempdb is where SQL Server stores temporary data such as work tables, sort space, row versioning information and etc.
  • User can create their own version of temporary tables and those are stored in Tempdb.
  • But this database is destroyed and recreated every time when we restart the instance of SQL Server.
Resource
  • The resource database is a hidden, read only database that holds the definitions of all system objects.
  • When we query system object in a database, they appear to reside in the sys schema of the local database, but in actually their definitions reside in the resource db.

Cloud Security: Is it Worth it?

Storing and managing corporate data by applying the cloud is becoming more and more popular. Companies grow, and it gets too expensive, and resources consuming to store their data on traditional servers. To prove it, look at the research conducted by Google in 2019 that includes insights for the cloud computing market for the next 10 years.

Around 80% of US respondents (about 1,100 businesses participated) revealed that they are thinking about cloud adoption by 2029. In 2019, only about 40% made a switch. 72% of businesses state that they’d like to automate security solutions by 2029, while now only 33% actually do it.

What do these numbers tell us? That companies seem to be suspicious about cloud security and prefer traditional on-premises data storage to the cloud environment. Why are they afraid to entrust cloud providers with their data? What to do to get rid of this fear? How to prove that the future of security is after the cloud?

In our article, we aim to answer these questions and more, but first, you need to be able to identify the reasons why companies have cloud-related trust issues. The first step in eliminating a problem is identifying it, let’s do it together!
