IEC 62351

IEC 62351

IEC 62351 is a stan­dard devel­oped to han­dle the secu­ri­ty of TC 57 series of pro­to­cols includ­ing IEC 60870–5 series, IEC 60870–6 series, IEC 61850 series, IEC 61970 series & IEC 61968 series.

The dif­fer­ent secu­ri­ty objec­tives include the authen­ti­ca­tion of data trans­fer through dig­i­tal sig­na­tures, pre­ven­tion of eaves­drop­ping and play­back as well as spoof­ing, and intru­sion detection.

    Cyber Security

    IEC 62351 is a stan­dard devel­oped to han­dle the secu­ri­ty of TC 57 series of pro­to­cols includ­ing IEC 60870–5 series, IEC 60870–6 series, IEC 61850 series, IEC 61970 series & IEC 61968 series.

    The dif­fer­ent secu­ri­ty objec­tives include the authen­ti­ca­tion of data trans­fer through dig­i­tal sig­na­tures, pre­ven­tion of eaves­drop­ping and play­back as well as spoof­ing, and intru­sion detection.

    IPsec (IP for “Inter­net Pro­to­col” and sec for “secure”) is a group of pro­to­cols to ensure the integri­ty, con­fi­den­tial­i­ty and authen­ti­ca­tion of data com­mu­ni­ca­tions over an IP network.

    IPsec is com­mon­ly used as a base for VPNs (Vir­tu­al Pri­vate Net­works), encrypt­ing the IP pack­ets and authen­ti­cat­ing the source where the pack­ets come from.

    Ter­mi­nal Access Con­troller Access-Con­trol Sys­tem Plus (TACACS+) is a pro­to­col devel­oped by Cis­co to han­dle authen­ti­ca­tion, autho­riza­tion, and account­ing (AAA) ser­vices and was released as an open stan­dard begin­ning in 1993.

    It is an exten­sion of its pre­de­ces­sor TACACS, encrypt­ing the full con­tent of each pack­et and pro­vides gran­u­lar con­trol (com­mand by com­mand autho­riza­tion) whilst oper­at­ing over TCP.

    Open­VPN is a vir­tu­al pri­vate net­work (VPN) pro­to­col and soft­ware for both client and serv­er applications.

    It imple­ments tech­niques to cre­ate secure point-to-point or site-to-site con­nec­tions in rout­ed or bridged con­fig­u­ra­tions and remote access facil­i­ties enabling peer authen­ti­ca­tion using pre-shared secret keys, cer­tifi­cates or usernames/passwords.

    Pub­lic key infra­struc­ture (PKI) refers to a range of tech­nolo­gies for authen­ti­cat­ing users and devices in order to secure the dig­i­tal trans­fer of infor­ma­tion for a range of net­work activ­i­ties such as e‑commerce, inter­net bank­ing and con­fi­den­tial email.

    It includes a set of roles, poli­cies, hard­ware, soft­ware and pro­ce­dures need­ed to cre­ate, man­age, dis­trib­ute, use, store and revoke dig­i­tal cer­tifi­cates and man­age pub­lic-key encryption.

    Expert Cyber Security 

    iGrid T&D enforces sev­er­al lay­ers of secu­ri­ty mea­sures guid­ed by the propo­si­tions of the IEC 62351 stan­dard to pro­tect its devices from all kinds of threats.

    Our hard­ened devices fea­ture Role Based Access Con­trol (RBAC) to avoid intrin­sic risks such as secu­ri­ty holes and unau­tho­rized actions by authen­ti­cat­ed users.
    In addi­tion to end-to-end encryp­tions via TSL/SSL, HTTPS, SSH and stan­dard pro­ce­dures for VPNs (e.g. Open­VPN), its com­mu­ni­ca­tion can also be secured with net­work con­trol meth­ods such as fire­walls, IP fil­ters, ACL or TCP port blocks.

    iGW‑S Substation Gateway

    Pow­er­ful and reli­able sub­sta­tion gate­way, able to run either in stand­alone or redun­dant modes, with an embed­ded Eth­er­net switch (4 ports) and IEC 61850 client and serv­er capabilities.

    iRTU – With I/Os for Direct Data Acquisition 

    Com­pact and scal­able bay con­troller which can act as IEC 61850 client or serv­er, fea­tur­ing con­fig­urable I/O boards for direct data acqui­si­tion, high-pre­ci­sion time­stamp­ing and an option­al Eth­er­net switch for addi­tion­al Eth­er­net ports.

    iControl SCADA

    High-per­for­mance SCADA for the visu­al­iza­tion and con­trol of sub­sta­tion data.
