Upgrading OpenSSL

There are two methods available for upgrading the OpenSSL cryptographic software library.

Method 1: Obtaining an Upgrade Package from the Debian Security Update Repository

1.Make sure the APE module has access to the Internet.

2.Log in or gain root access to the APE line module.

3.Using vim or nano, open the file /etc/opt/sources.list and add the following line:

dep http://security.debian.org wheezy/updates main

This points Debian's upgrade system (referred to as APT) to Debian's online Security Update Repository for Debian 7. APE line modules based on Debian 6 are not vulnerable to Heartbleed and require no update.

4.At the command prompt, type the following commands to upgrade the OpenSSL cryptographic software library:

apt-get update

apt-getinstall openssl libssl1.0.0

Make sure both commands execute without errors.

5.Make sure OpenSSL has been upgraded to version 1.0.1e-2+deb7u6 or later. For more information, refer to Chapter 2, Verifying the OpenSSL Version.

6.If further security updates from Debian's Security Update Repository are not desired, remove the lines previously added to /etc/apt/sources.list.

Method 2: Obtaining an Upgrade Package from Siemens Customer Support

1.Request the following Debian packages from Siemens Customer Support:

openssl_1.0.1e-2+deb7u6_i386.deb

libssl1.0.0_1.0.1e-2+deb7u6_i386.deb

2.Once obtained, upload the files to the APE line module via SFTP, SCP or a USB memory media.

3.Log in or gain root access to the APE line module.

4.At the command prompt, type the following command to upgrade the OpenSSL cryptographic library:

dpkg -i openssl_1.0.1e-2+deb7u6_i386.deb libssl1.0.0_1.0.1e-2+deb7u6_i386.deb

5.Delete the .deb files by typing:

rm openssl_1.0.1e-2+deb7u6_i386.deb libssl1.0.0_1.0.1e-2+deb7u6_i386.deb

AN25 specifications

The Siemens AN25 is a cutting-edge automation solution designed for modern industrial applications. This versatile device brings together advanced technologies to enhance efficiency, reliability, and productivity in diverse sectors, including manufacturing, process automation, and logistics.

One of the key features of the Siemens AN25 is its ability to integrate seamlessly with existing industrial systems. This integration is facilitated by its compatibility with various communication protocols such as PROFINET and EtherNet/IP, allowing it to connect easily to other devices and systems within the automation ecosystem. This ready-to-connect capability helps minimize downtime during implementation and ensures smooth operation across different platforms.

The AN25 is powered by advanced processing capabilities, featuring a high-performance CPU that enables real-time data processing. This is crucial for applications that require immediate response times, such as robotics and high-speed production lines. The device also supports edge computing, which allows for data analysis at the source rather than sending all information back to a central server. This reduces latency and improves decision-making efficiency.

Another notable feature of the Siemens AN25 is its robust security architecture. With increasing cyber threats in industrial environments, the AN25 employs multiple layers of security, including user authentication, encryption, and secure firmware updates. This ensures that sensitive data remains protected while maintaining compliance with industry standards.

The AN25 is also designed for scalability. Users can easily expand the system by adding new modules or devices as their needs evolve, without requiring a complete overhaul of the existing infrastructure. This scalability makes it ideal for businesses anticipating growth or changes in operational requirements.

Durability is a critical characteristic of the Siemens AN25, which is built to withstand challenging industrial conditions. It is housed in a rugged enclosure that can tolerate extreme temperatures, vibrations, and exposure to dust and moisture. This resilience ensures prolonged operational life and reduces maintenance costs, providing greater return on investment.

In summary, the Siemens AN25 represents a significant advancement in industrial automation technology, offering features such as seamless integration, real-time data processing, robust security, scalability, and durability. Whether used in manufacturing, process automation, or logistics, the AN25 stands out as a reliable and efficient solution for navigating the complexities of modern industrial environments.
