7 Strategies to Developing SCADA Security:

Development of the industry, makes more complex problems faced related to control systems and security. In general, SCADA is still relevant enough to be used as a control system that is capable of controlling several machines control in different areas. In line with the increasing fragility of attacks against SCADA cyber attack that also need proper treatment.

SCADA security systems today require the integration of several functions of controllers such as firewalls, proxy servers, operating systems, coating application systems, communications, and policies and procedures. For the implementation of SCADA security strategy then you need security measures to keep the network as follows: 

1. BORDER ROUTER AND FIREWALLS

Cyber ​​attacks are usually carried out by sending the software to penetrate the internal private network. If the security system is not protected SCADA Firewalls are configured correctly then your security system is not good enough to protect passwords, IP addresses, files and so on.

2. PROXY SERVERS

Packets of data sent or passing through TCP / IP should have been entered in the resource control layer applications such as Hyper Text Transfer Protocol (HTTP) and Simple Mail Transfer Protocol (SMTP). To strengthen the security system SCADA proxy server acts as a firewall to protect the traffic between a protected network and the Internet. These systems are relatively safe although security with proxy servers will not eliminate the threat of the layer attacks application.

3. OPERATING SYSTEMS

As the brain of the computer system, the operating system became the main target of cyber attacks. There are 2 options for securing this system namely through the operating system upgrade to newer versions or migration by replacing opeating system to a higher version. For the safety of Operating Systems should really upgrade to the latest version and there is no compromise for any irregularities that exist.

4.  APPLICATIONS

Some viruses are intentionally sent to undermine the security of SCADA systems such as buffer overruns, worms, Trojan Horse, Active-X5 codes, and other malicious programs that we need to anticipate. Viruses and works by paralyzing anti-virus software and bypassing the firewall as if it had no security protection there

5. POLICIES AND PROCEDURES

In addition to programs designed to address cyber attacks, it is necessary also the policies that govern the discipline of the user in performing the procedure. The policies and procedures include the selection of a secure password with a combination for example with at least one symbol, a capital letter and a number, and should be more than eight characters.

6. SCADA FIREWALLS

SCADA network security can be strengthened with layers of firewalls between the system SCADA network and the Internet. System security threats are often due to internal factors such as the employee who accidentally did not record the procedures performed and it turns out it can be compromised using the hacking method that is similar to what he did.

7. SCADA INTERNAL NETWORK DESIGN

Internal SCADA network must have its own IP and run by using intelligent switches and sub-masking techniques appropriate to protect the system from cyber attack. The use of Ethernet Wireless and Wired Equivalent Protocol (WEP) can be an alternative to change the default name of the Service Set Identifier6 (SSID).

Conclusion

Supervisory Control and Data Acquisition (SCADA) system is the important control processes in many countries. This system performs important functions vital to many companies such as electric power companies, gas - natural, petroleum, water treatment, sewage treatment, and even the railway. However, considerations in terms of safety in the design of this system have received less attention, so the potential for interference from unauthorized access can occur. This review above will provide you several important phases to protect your system from cyber attack. By learning more methods you will get alternatives and the implementation of effective and economical control system. 

PLC Scan Cycle - Leading industrial automation companies in India providing PLC SCADA DCS training in Chennai. Best PLC training center in Chennai. Automation in India,

PLC Scan Cycle

A plc executes an initialization step when placed in run mode then repeatedly executes scan cycle sequence. Basic PLC has three steps.

1.       An input scan

2.       A user program scan

3.       An output scan.

1.       Input Scan :

During this process data is taken from all input modules in system and placed into an area of PLC memory referred to as input image area.

In this scan, input terminals are read and the input image area is updated accordingly.

2.       User program Scan:

During program scan, Data in input image area is applied to user program, the user program is executed and output image area is updated.

In this scan,

·         Data in input image area is applied to user program

·         The program executed

·         The output image area updated

3.       Output Scan:

During the output scan, data is taken from the output image area and sent to all output modules in the system.

In this scan data associated with output image area is transferred to output terminals.

We should understand that input, program, and output scans are separate and independent functions. Any changes in status of input devices during the program or output scan are not recognized until the next input.

Program (Ladder logic) scanning typically takes place left to right across each rung and from the top to bottom rungs, in order known as rung scanning. This method used in plc like Allen Bradley.

Another method used by Modicon/Schneider Automation is known as column scanning.

In this processor looks at first contact at Top left corner and reads the first column from top to bottom. Next reads the second column from top to bottom and so on.

We use rung or column method according to PLC we use.

Rung Scanning:

Column Scanning:

For example we have simple operation below:

Two rung ladder logic program:

Program in logix pro simulator:

Program with energized input ( Here after first rung input and output process it automatically selects another rung from left side.)

Data Base Communication(PLC) -Industrial Automation in India | PLC SCADA DCS Training in Chennai,

Data Base Communication(PLC)

           

Data base communication is communication between different software.  We might have data in Microsoft word or Microsoft Excel or other software and we need access for our program then this function of PLC helps us to communicate with them.

We take example of Microsoft Excel.

First we should open Microsoft excel then go to Excel Menu and select Excel option formula.

         Tick on working of formula R₁C₁ reference style. Here we save our file with name ‘g’ at any place you want.

Now go to RS View 32 (SCADA). Go to Configuration à Go to Configure then Add access name as below:

Access à Ritesh (Let us suppose)

Application nameà Excel

Topic Name à g.xlsx (here g is file name of excel and xlsx is extension name for Microsoft excel)

                DDE ( Fill the DDE which allow excel user to change in data in PLC.

                  Click Ok.

Take text display from menu and give its Tag name ‘a’ and select its type I/O real.

Access name à Ritesh

Item à Cell address (R₁C₁)

Here we run our scada program. When we change the value in Display, Same data pasted in Excel in Row first, column first. Same happens when we change in R₁C₁ of Excel, the data also changes in display of Scada.

Change in excel from scada

Scada display:

Change in excel:

Change in scada from excel

Excel display:

Scada display:

The valuable effect of this function is:

1.       User can access data from any file.

2.       Programmer can control multiple programs by single frame.

3.       A simple user (Not a PLC programmer) can control the full system with their best command software like Microsoft Office.

Note: There are different extension names for different software as already taken by manufacturer company.

Simatic Step 7 -Industrial Automation in India | PLC SCADA DCS Training in Chennai,

Data Blocks in Simatic Step 7 Siemens :

Data Blocks (DBs) can be used by your program to save data in the CPU. Your hard disk contains up to 8 Kbytes(8192Bytes) space. There are two types of data blocks. Global DBs, where all OBs, FBs and FCs read all saved data or can even write in the DB and local instance DBs, which are assigned a particular FB. In the DBs, different data types (e.g. BOOL or WORD) can be saved in arbitrary order. This structuring of a DB follows through input in a table with the tool LAD, STL, FBD - S7 Block Programming.
In the program structure from STEP 7, data blocks are found as follows:

Data blocks are generated and opened like program blocks in the tool LAD, STL, FBD: Programblocks. They serve e.g. for the saving of data and system states.

Before create Data Blocks (DBs), we must understand about addressing Data in Simatic Step7. Figure 2 show the addressing data elements in Simatic Step7. There is 3 elementary data type:

• Bit data Type (Bool, Byte, Word, DWord, Char)
• Mathematical data type (Int, Dint, Real)
• Time types (s5Time, Time, Date, Time_of_Day)

In the figure 2, 1 box represent 1 Bit memory. 1 Bool have length 1 Bit, and 1 Byte have length 8 Bit. For more detail you can see in table below

Type	Size in Bit	Range and Number Notation
Bool	1	True/False
