Admission control. Digital access to the storage media of personal data must generally be protected against unauthorized access by means of password-protected access and passwords are randomly generated by an encrypted password manager. Access data and passwords in particular must never be stored locally, but only in a SOC2-certified password management tool. Also, sharing of newly created login credentials or shared access is never done unencrypted via standard communication channels, but exclusively by means of the deployed password management software. In this way, user accesses are centrally managed, documented and their validity regularly checked. As a matter of principle, initial passwords must be changed immediately after they are received and stored in a private password container in the certified password management tool. E-mails are only sent and read via the TLS-encrypted domain belonging to the company. In addition, screen workstations are automatically locked after two minutes and must be unlocked by re-authentication.
Admission control. The feasibility of a request satisfaction should be checked before including the request in the system. Based on the requests already presented in the process’s local queue, the admission control should firstly verify if a process request can be locally satisfied. If such is the case, a global admission policy is performed. Local validation decision policy: As previously explained, requests of a process’s local queue Q are sorted by their response time deadline. Upon reception of a new request R, the process computes the potential position P of R in its queue. It then evaluates if the satisfaction of R is feasible or not. R is feasible if: (1) requests before P in Q will respect R’s constraints after its insertion; (2) R will respect the constraints of the next requests after position P in Q which have already been validated by the site. In order to respect these two conditions, it is necessary to consider the scenario where all requests are satisfied at their deadline. Therefore, in order to ensure (1), the deadline of the request before P (denoted P −1) plus its CS execution duration plus the latency to send the token from P − 1’s requesting node to R’s should not violate R’s deadline. Analogously, in order to ensure (2), the deadline of R plus its CS execution duration plus the latency to send the token between R’s requesting node and P + 1’s (i.e. the requesting node just after P ) in Q should not violate P + 1’s deadline. Global validation decision policy: If a request is locally satisfied according to the local decision policy then the process sends a request message to its father (same principle as Ray- mond’s algorithm) which includes the maximum deadline for the response and the duration of the CS. Similarly, the father also submits the request to the admission control. Such a mechanism is recursively applied till the root node. Consequently, the root node will be aware of all the pending requests in the system. If the request is rejected by a node N (a node in the path between the requesting node and the root, both of them included), it sends a reject message to its child that belongs to the path towards the requesting node. Such a message is forwarded until the requesting process which will finally discard it. On the other hand, in the case of a request acceptance, we propose two approaches for notification: • Acknowledgement approach: The requesting process should wait for an acknowledgement message from its father which then confirms that its ...

Admission control. Measures to limit admission of unauthorized persons to systems where personal data is used or processed with electronic data processing devices. • Safeguarding of physical network infrastructure • Firewall for internal networks against external vulnerabilities • Control of use for electronic data processing • Regulations and instructions of admission control • Control and identification of authorized persons • Logging of use for entry rights • Admission only with User-ID and password only • Separation of function principle when granting entry authorization • Identification of terminal or terminal user (e.g.: login with user-ID and password) • Automatic screensaver protection in case of inactivity • Lockable terminals and decentralized IT-systems • Safeguarding of electronic data processing systems correspondent with the requirements • Functional and/or timely limited use of terminals
Admission control. Whenever a new device attempts to enter the MANET, it needs to broadcast its own local output behavior profile to the current members. Initially, the members will check whether the new device is blacklisted. If it passes this check, the mem- bers proceed to compute the distance between their own input profile and the output profile of the newcomer. If the distance is within its own local threshold of normalcy, the member emits a favorable vote vi = 1. The final MANET vote v can be expressed as: 1 Σ vi = 0 if d(Pi,in, Pnew,out) > τi vi = 1 if d(Pi,in, Pnew,out) ≤ τi where n is the number of members in the MANET, τi is the threshold of member i, Xx,in is the input behavior profile of member i and Pnew,out is the output behavior profile of the newcomer. If t or more members of the MANET emit a favorable vote vi = 1, the newcomer is admitted. Otherwise, the newcomer is rejected and added to a grey list that keeps track of the number of admission attempts by the device. If a device exceeds a fixed number of attempts, it will be added to a blacklist. In order to keep the latest updates, grey and blacklists are exchanged among MANET members. Upon acceptance of the newcomer, all the members of the MANET submit their output behavior profiles to the new member. The new member stores the profiles together with the distance measures between its own input profile and the output profiles of the remaining members of the MANET in its local table. Then, Q1 Q5 Q6 Q3 Q4 Q2 t=4 P ? Pnew ? new s1 P ? s6 new s 3 Pnew ? Pnew ? P new ? s2 Pnew
Admission control. The following implemented measures prevent unauthorized persons from accessing the data processing systems: ● Authentication with user and password ● Authentication with biometric data ● Use of anti-virus software ● Use of firewalls ● Use of mobile device management ● Use of VPN technology for remote accesses ● Encryption of data media ● Automatic desktop lock ● Encryption of notebooks / tablets ● Management of user permissions ● Creation of user profiles ● Central password rules ● Use of 2-factor authentication ● Logging of visitors (e.g. visitor book) ● General corporate policy on data protection or security ● Corporate policy for secure passwords ● Corporate "Delete/Destroy" policy ● Corporate "Cleandesk" policy ● General instruction to manually lock desktop when leaving workstation

Imple- mented Measure Y Access control guidelines and regulations Y Security areas are clearly defined Y Appropriate implementation of measures to secure the buildings Y Appropriate implementation of measures to secure Datacenter Access Y Security also outside working hours by alarm system and/or plant security Y Access only for authorized persons (company employees and external persons) Y Regulation for external parties Y Use of security badges Y Key Management Y Implementation of locks Y External staff is accompanied by Prodware staff
Admission control. Measures that prevent unauthorized persons from processing or using data protected by data protection laws. Description of the admission control system: · Access to appointman systems is only possible via individual VPN connections. · Access to server management is ensured by two-factor authentication. · Passwords are generated via local password managers with a minimum length of 12 characters and 2 special characters and (depending on the system) are provided with an expiry date for the regular change (6 months). · Use of firewalls.
Admission control. This class is used to interpret and analyse customers QoS requirements and receive the pre-scheduling result from scheduler, and then it uses admission control criteria to decide whether to accept or reject the request. •
